10#
11# Unless otherwise specified, the source for data through 1990 is:
12# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
13# San Diego: ACS Publications, Inc. (2003).
14# Unfortunately this book contains many errors and cites no sources.
15#
16# Many years ago Gwillim Law wrote that a good source
17# for time zone data was the International Air Transport
18# Association's Standard Schedules Information Manual (IATA SSIM),
19# published semiannually.  Law sent in several helpful summaries
20# of the IATA's data after 1990.  Except where otherwise noted,
21# IATA SSIM is the source for entries after 1990.
22#
23# Another source occasionally used is Edward W. Whitman, World Time Differences,
24# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
25# I found in the UCLA library.
26#
27# For data circa 1899, a common source is:
28# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
29# https://www.jstor.org/stable/1774359
30#
31# For Russian data circa 1919, a source is:
32# Byalokoz EL. New Counting of Time in Russia since July 1, 1919.
33# (See the 'europe' file for a fuller citation.)
34#
35# A reliable and entertaining source about time zones is
36# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
37#
38# The following alphabetic abbreviations appear in these tables:
39#	     std  dst
40#	     LMT	Local Mean Time
41#	2:00 EET  EEST	Eastern European Time
42#	2:00 IST  IDT	Israel

49#	9:00 JST  JDT	Japan
50#	9:00 KST  KDT	Korea when at +09
51#	9:30 ACST	Australian Central Standard Time
52# Otherwise, these tables typically use numeric abbreviations like +03
53# and +0330 for integer hour and minute UT offsets.  Although earlier
54# editions invented alphabetic time zone abbreviations for every
55# offset, this did not reflect common practice.

87# Armenia
88# From Paul Eggert (2006-03-22):
89# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)
90# in spring 1991, then to 4:00 with no DST in fall 1995, then
91# readopting Russian DST in 1997.  Go with Shanks & Pottenger, even
92# when they disagree with others.  Edgar Der-Danieliantz
93# reported (1996-05-04) that Yerevan probably wouldn't use DST
94# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that
95# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
96# but started switching at 3:00s in 1998.
97

287# From Bob Devine (1988-01-28):
288# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
289# China is across 4 physical time zones, before Feb 1, 1986 only the
290# Peking (Beijing) time zone was recognized.  Since that date, China
291# has two of 'em - Peking's and Ürümqi (named after the capital of

329# I have investigated the timezones around 1970 on the

335# county is GMT+8 according to astro.com while Baiyu county is GMT+6
336# (could be true), for the moment I am assuming that those two

339# From Paul Eggert (2017-01-05):
340# Alois Treindl kindly sent me translations of the following two sources:
341#
342# (1)
343# Guo Qingsheng (National Time-Service Center, CAS, Xi'an 710600, China)
344# Beijing Time at the Beginning of the PRC
345# China Historical Materials of Science and Technology
346# (Zhongguo ke ji shi liao, 中国科技史料), Vol. 24, No. 1 (2003)
347# It gives evidence that at the beginning of the PRC, Beijing time was
348# officially apparent solar time!  However, Guo also says that the
349# evidence is dubious, as the relevant institute of astronomy had not
350# been taken over by the PRC yet.  It's plausible that apparent solar
351# time was announced but never implemented, and that people continued
352# to use UT+8.  As the Shanghai radio station (and I presume the
353# observatory) was still under control of French missionaries, it
354# could well have ignored any such mandate.
355#
356# (2)
357# Guo Qing-sheng (Shaanxi Astronomical Observatory, CAS, Xi'an 710600, China)
358# A Study on the Standard Time Changes for the Past 100 Years in China
359# [undated and unknown publication location]
360# It says several things:
361#   * The Qing dynasty used local apparent solar time throughout China.
362#   * The Republic of China instituted Beijing mean solar time effective
363#     the official calendar book of 1914.
364#   * The French Concession in Shanghai set up signal stations in
365#     French docks in the 1890s, controlled by Xujiahui (Zikawei)
366#     Observatory and set to local mean time.
367#   * "From the end of the 19th century" it changed to UT+8.
368#   * Chinese Customs (by then reduced to a tool of foreign powers)
369#     eventually standardized on this time for all ports, and it
370#     became used by railways as well.
371#   * In 1918 the Central Observatory proposed dividing China into
372#     five time zones (see below for details).  This caught on
373#     at first only in coastal areas observing UT+8.
374#   * During WWII all of China was in theory was at UT+7.  In practice
375#     this was ignored in the west, and I presume was ignored in
376#     Japanese-occupied territory.
377#   * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
378#   * The five-zone plan was resurrected after WWII and officially put into
379#     place (with some modifications) in March 1948.  It's not clear
380#     how well it was observed in areas under Nationalist control.
381#   * The People's Liberation Army used UT+8 during the civil war.
382#
383# An AP article "Shanghai Internat'l Area Little Changed" in the
384# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is
385# different - the occupied districts going by Tokyo time, an hour
386# ahead of that prevailing in the rest of Shanghai."  Guess that the
387# Xujiahui Observatory was under French control and stuck with UT +08.
388#
389# In earlier versions of this file, China had many separate Zone entries, but
390# this was based on what were apparently incorrect data in Shanks & Pottenger.
391# This has now been simplified to the two entries Asia/Shanghai and
392# Asia/Urumqi, with the others being links for backward compatibility.
393# Proposed in 1918 and theoretically in effect until 1949 (although in practice
394# mainly observed in coastal areas), the five zones were:
395#
396# Changbai Time ("Long-white Time", Long-white = Heilongjiang area) UT +08:30
397# Now part of Asia/Shanghai; its pre-1970 times are not recorded here.
398# Heilongjiang (except Mohe county), Jilin
399#
400# Zhongyuan Time ("Central plain Time") UT +08
401# Now part of Asia/Shanghai.
402# most of China
403# Milne gives 8:05:43.2 for Xujiahui Observatory time; round to nearest.
404# Guo says Shanghai switched to UT +08 "from the end of the 19th century".
405#
406# Long-shu Time (probably as Long and Shu were two names of the area) UT +07
407# Now part of Asia/Shanghai; its pre-1970 times are not recorded here.
408# Guangxi, Guizhou, Hainan, Ningxia, Sichuan, Shaanxi, and Yunnan;
409# most of Gansu; west Inner Mongolia; east Qinghai; and the Guangdong
410# counties Deqing, Enping, Kaiping, Luoding, Taishan, Xinxing,
411# Yangchun, Yangjiang, Yu'nan, and Yunfu.
412#
413# Xin-zang Time ("Xinjiang-Tibet Time") UT +06
414# This region is now part of either Asia/Urumqi or Asia/Shanghai with
415# current boundaries uncertain; times before 1970 for areas that
416# disagree with Ürümqi or Shanghai are not recorded here.
417# The Gansu counties Aksay, Anxi, Dunhuang, Subei; west Qinghai;
418# the Guangdong counties  Xuwen, Haikang, Suixi, Lianjiang,
419# Zhanjiang, Wuchuan, Huazhou, Gaozhou, Maoming, Dianbai, and Xinyi;
420# east Tibet, including Lhasa, Chamdo, Shigaise, Jimsar, Shawan and Hutubi;

425#
426# Kunlun Time UT +05:30
427# This region is now in the same status as Xin-zang Time (see above).

432
433# From Luther Ma (2009-10-17):
434# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
435# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
436# but have no need of it. All planes, trains, and schools function on
437# what is called "Beijing time." When Han make an appointment in Chinese
438# they implicitly use Beijing time.
439#
440# On the other hand, ethnic Uyghurs, who make up about half the
441# population of Xinjiang, typically use "Xinjiang time" which is two
442# hours behind Beijing time, or UT +06. The government of the Xinjiang
443# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
444# local governments such as the Ürümqi city government use both times in
445# publications, referring to what is popularly called Xinjiang time as
446# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language
447# they almost invariably use Xinjiang time.
448#
449# (Their ethnic Han compatriots would typically have no clue of its
450# widespread use, however, because so extremely few of them are fluent in
451# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
452#
453# (...As with the rest of China there was a brief interval ending in 1990
454# or 1991 when summer time was in use.  The confusion was severe, with
455# the province not having dual times but four times in use at the same
456# time. Some areas remained on standard Xinjiang time or Beijing time and
457# others moving their clocks ahead.)
458
459# From Luther Ma (2009-11-19):
460# With the risk of being redundant to previous answers these are the most common
461# English "transliterations" (w/o using non-English symbols):
462#
463# 1. Wulumuqi...
464# 2. Kashi...
465# 3. Urumqi...
466# 4. Kashgar...
467# ...
468# 5. It seems that Uyghurs in Ürümqi has been using Xinjiang since at least the
469# 1960's. I know of one Han, now over 50, who grew up in the surrounding
470# countryside and used Xinjiang time as a child.
471#
472# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
473# start date for Xinjiang time.
474#
475# Without having access to local historical records, nor the ability to legally
476# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
477# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
478# not be using Beijing time, but some local time.)
479
480# From David Cochrane (2014-03-26):
481# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986:
482# https://content.time.com/time/magazine/article/0,9171,960684,00.html
483
484# From Luther Ma (2014-04-22):
485# I have interviewed numerous people of various nationalities and from
486# different localities in Xinjiang and can confirm the information in Guo's
487# report regarding Xinjiang, as well as the Time article reference by David
488# Cochrane.  Whether officially recognized or not (and both are officially
489# recognized), two separate times have been in use in Xinjiang since at least
490# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time;
491# and Beijing Time.  There is no confusion in Xinjiang as to which name refers
492# to which time. Both are widely used in the province, although in some
493# population groups might be use one to the exclusion of the other.  The only
494# problem is that computers and smart phones list Ürümqi (or Kashgar) as
495# having the same time as Beijing.
496
497# From Paul Eggert (2014-06-30):
498# In the early days of the PRC, Tibet was given its own time zone (UT +06)
499# but this was withdrawn in 1959 and never reinstated; see Tubten Khétsun,
500# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN
501# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x.
502# As this is before our 1970 cutoff, Tibet doesn't need a separate zone.
503#
504# Xinjiang Time is well-documented as being officially recognized.  E.g., see
505# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government"
506# <http://www.sinkiang.gov.cn/service/ourworking/> (2014-04-22).
507# Unfortunately, we have no good records of time in Xinjiang before 1986.
508# During the 20th century parts of Xinjiang were ruled by the Qing dynasty,
509# the Republic of China, various warlords, the First and Second East Turkestan
510# Republics, the Soviet Union, the Kuomintang, and the People's Republic of
511# China, and tracking down all these organizations' timekeeping rules would be
512# quite a trick.  Approximate this lost history by a transition from LMT to
513# UT +06 at the start of 1928, the year of accession of the warlord Jin Shuren,
514# which happens to be the date given by Shanks & Pottenger (no doubt as a
515# guess) as the transition from LMT.  Ignore the usage of +08 before
516# 1986-02-01 under the theory that the transition date to +08 is unknown and
517# that the sort of users who prefer Asia/Urumqi now typically ignored the
518# +08 mandate back then.

627# From smallufo (2010-04-03):
628# According to Taiwan's CWB [Central Weather Bureau],
629# http://www.cwb.gov.tw/V6/astronomy/cdata/summert.htm
630# Taipei has DST in 1979 between July 1st and Sep 30.
631
632# From Yu-Cheng Chuang (2013-07-12):
633# On Dec 28, 1895, the Meiji Emperor announced Ordinance No. 167 of
634# Meiji Year 28 "The clause about standard time", mentioned that
635# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
636# (both in Okinawa) adopt the Western Standard Time which is based on
637# 120E. The adoption began from Jan 1, 1896. The original text can be
638# found on Wikisource:
639# https://ja.wikisource.org/wiki/標準時ニ關スル件_(公布時)
640# ... This could be the first adoption of time zone in Taiwan, because
641# during the Qing Dynasty, it seems that there was no time zone
642# declared officially.
643#
644# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
645# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
646# revision in the ordinance No. 167 of Meiji year 28 about standard
647# time", in which abolished the adoption of Western Standard Time in
648# western islands (listed above), which means the whole Japan
649# territory, including later occupations, adopt Japan Central Time
650# (UT+9). The adoption began on Oct 1, 1937. The original text can
651# be found on Wikisource:
652# https://ja.wikisource.org/wiki/明治二十八年勅令第百六十七號標準時ニ關スル件中改正ノ件
653#
654# That is, the time zone of Taipei switched to UT+9 on Oct 1, 1937.
655
656# From Yu-Cheng Chuang (2014-07-02):
657# I've found more evidence about when the time zone was switched from UT+9
658# back to UT+8 after WW2.  I believe it was on Sep 21, 1945.  In a document
659# during Japanese era [1] in which the officer told the staff to change time
660# zone back to Western Standard Time (UT+8) on Sep 21.  And in another
661# history page of National Cheng Kung University [2], on Sep 21 there is a
662# note "from today, switch back to Western Standard Time".  From these two
663# materials, I believe that the time zone change happened on Sep 21.  And
664# today I have found another monthly journal called "The Astronomical Herald"
665# from The Astronomical Society of Japan [3] in which it mentioned the fact
666# that:
667#
668# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
669# the time at 135E (GMT+9)
670#
671# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
672# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
673# as well as Yaeyama and Miyako islands, adopted a new time zone called
674# Western Standard Time, which is in GMT+8.
675#
676# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
677# territories of Japan adopted the same time zone, which is Central Standard
678# Time.

687# Yu-Cheng Chuang (2014-07-03):
688# I finally have found the real official gazette about changing back to
689# Western Standard Time on Sep 21 in Taiwan.  It's Taiwan Governor-General
690# Bulletin No. 386 in Showa 20 years (1945), published on Sep 19, 1945. [1] ...
691# [It] abolishes Bulletin No. 207 in Showa 12 years (1937), which is a local
692# bulletin in Taiwan for that Ordinance No. 529. It also mentioned that 1am on
693# Sep 21, 1945 will be 12am on Sep 21.  I think this bulletin is much more
694# official than the one I mentioned in my first mail, because it's from the
695# top-level government in Taiwan. If you're going to quote any resource, this
696# would be a good one.

700# From Yu-Cheng Chuang (2014-07-02):
701# In 1946, DST in Taiwan was from May 15 and ended on Sep 30. The info from

712#
713# Here is a brief translation:
714#
715#   The Summer Time this year is adopted from midnight Apr 15 until Sep 20
716#   midnight. To save (energy?) consumption, we're expanding Summer Time
717#   adoption till Oct 31 midnight.
718#
719# The Central Weather Bureau website didn't mention that, however it can
720# be found from historical government announcement database.
721
722# From Paul Eggert (2014-07-03):
723# As per Yu-Cheng Chuang, say that Taiwan was at UT +09 from 1937-10-01
724# until 1945-09-21 at 01:00, overriding Shanks & Pottenger.
725# Likewise, use Yu-Cheng Chuang's data for DST in Taiwan.

819# Georgia
820# From Paul Eggert (1994-11-19):
821# Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
822# an hour recently, due to a law proposed by Zurab Murvanidze,
823# an MP who went on a hunger strike for 11 days to force discussion about it!
824# We have no details, but we'll guess they didn't move the clocks back in fall.
825#
826# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
827# Instead of putting back clocks at the end of October, Georgia
828# will stay on daylight savings time this winter to save energy,
829# President Eduard Shevardnadze decreed Wednesday.
830#
831# From the BBC via Joseph S. Myers (2004-06-27):
832#
833# Georgia moved closer to Western Europe on Sunday...  The former Soviet
834# republic has changed its time zone back to that of Moscow.  As a result it
835# is now just four hours ahead of Greenwich Mean Time, rather than five hours
836# ahead.  The switch was decreed by the pro-Western president of Georgia,
837# Mikheil Saakashvili, who said the change was partly prompted by the process
838# of integration into Europe.
839
840# From Teimuraz Abashidze (2005-11-07):
841# Government of Georgia ... decided to NOT CHANGE daylight savings time on
842# [Oct.] 30, as it was done before during last more than 10 years.
843# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
844# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
845# about it.  As far as I can find, I was told, that there is no document,
846# because we just DIDN'T ISSUE document about switching to winter time....

903# In January 1906, several thousand cotton-mill workers rioted on the

907
908# From Paul Eggert (2017-04-20):
909# Good luck trying to nail down old timekeeping records in India.
910# "... in the nineteenth century ... Madras Observatory took its magnetic
911# measurements on Göttingen time, its meteorological measurements on Madras
912# (local) time, dropped its time ball on Greenwich (ocean navigator's) time,
913# and distributed civil (local time)." -- Bartky IR. Selling the true time:
914# 19th-century timekeeping in america. Stanford U Press (2000), 247 note 19.
915# "A more potent cause of resistance to the general adoption of the present
916# standard time lies in the fact that it is Madras time.  The citizen of
917# Bombay, proud of being 'primus in Indis' and of Calcutta, equally proud of
918# his city being the Capital of India, and - for a part of the year - the Seat
919# of the Supreme Government, alike look down on Madras, and refuse to change
920# the time they are using, for that of what they regard as a benighted
921# Presidency; while Madras, having for long given the standard time to the
922# rest of India, would resist the adoption of any other Indian standard in its
923# place." -- Oldham RD. On Time in India: a suggestion for its improvement.
924# Proceedings of the Asiatic Society of Bengal (April 1899), 49-55.
925#
926# "In 1870 ... Madras time - 'now used by the telegraph and regulated from the
927# only government observatory' - was suggested as a standard railway time,
928# first to be adopted on the Great Indian Peninsular Railway (GIPR)....
929# Calcutta, Bombay, and Karachi, were to be allowed to continue with their

935# This lists +052110 as Madras local time used in railways, and says that on
936# 1906-01-01 railways and telegraphs in India switched to +0530.  Some
937# municipalities retained their former time, and the time in Calcutta
938# continued to depend on whether you were at the railway station or at
939# government offices.  Government time was at +055320 (according to Shanks) or
940# at +0554 (according to the Indian Year Book).  Railway time is more
941# appropriate for our purposes, as it was better documented, it is what we do
942# elsewhere (e.g., Europe/London before 1880), and after 1906 it was
943# consistent in the region now identified by Asia/Kolkata.  So, use railway
944# time for 1870-1941.  Shanks is our only (and dubious) source for the
945# 1941-1945 data.

973# From Paul Eggert (2007-03-10):
974# Here is another correction to Shanks & Pottenger.
975# JohnTWB writes that Japanese forces did not surrender control in
976# Indonesia until 1945-09-01 00:00 at the earliest (in Jakarta) and
977# other formal surrender ceremonies were September 9, 11, and 13, plus
978# September 12 for the regional surrender to Mountbatten in Singapore.
979# These would be the earliest possible times for a change.
980# Régimes horaires pour le monde entier, by Henri Le Corre, (Éditions

982# from UT +09 to +07:30 on 1945-09-23, and gives 1944-09-01 for Jayapura
983# (Hollandia).  For now, assume all Indonesian locations other than Jayapura
984# switched on 1945-09-23.

1036# From Roozbeh Pournader (2003-03-15):
1037# This is an English translation of what I just found (originally in Persian).
1038# The Gregorian dates in brackets are mine:
1039#
1040#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
1041#	No. 16760/T233 H				1370/6/10 [1991-09-01]
1042#
1043#	The Rule About Change of the Official Time of the Country
1044#
1045#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
1046#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
1047#	of the Country's Organization for Official and Employment Affairs,
1048#	and referring to the law for equating the working hours of workers
1049#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
1050#	for synchronizing the official times of the country, agreed that:
1051#
1052#	The official time of the country will should move forward one hour
1053#	at the 24[:00] hours of the first day of Farvardin and should return
1054#	to its previous state at the 24[:00] hours of the 30th day of
1055#	Shahrivar.
1056#
1057#	First Deputy to the President - Hassan Habibi
1058#
1059# From personal experience, that agrees with what has been followed
1060# for at least the last 5 years.  Before that, for a few years, the
1061# date used was the first Thursday night of Farvardin and the last
1062# Thursday night of Shahrivar, but I can't give exact dates....
1063#
1064# From Roozbeh Pournader (2005-04-05):
1065# The text of the Iranian law, in effect since 1925, clearly mentions
1066# that the true solar year is the measure, and there is no arithmetic
1067# leap year calculation involved.  There has never been any serious
1068# plan to change that law....
1069#
1070# From Paul Eggert (2006-03-22):
1071# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
1072# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
1073# stopping after 2037 when 32-bit time_t's overflow.
1074# That cal-persia used Birashk's approximation, which disagrees with the solar
1075# calendar predictions for the year 2025, so I corrected those dates by hand.
1076#
1077# From Oscar van Vlijmen (2005-03-30), writing about future
1078# discrepancies between cal-persia and the Iranian calendar:
1079# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
1080# the vernal equinox and that gets so close to 12:00 some local
1081# Iranian time that the definition of the correct location needs to be
1082# known exactly, amongst other factors.  2157 is even closer:
1083# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
1084# no interpretation problem whatsoever.  By the way, another instant
1085# in the near future where there will be a discrepancy between
1086# arithmetical and astronomical Iranian calendars will be in 2058:
1087# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
1088# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
1089# 2058-03-21 for 1 Farvardin 1437 (astronomical).
1090#

1176# From Jonathan Lennox (2000-06-12):
1177# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
1178# the U.S. edition) on the Iraqi Kurds contains a paragraph:
1179# "The three northern provinces ... switched their clocks this spring and
1180# are an hour ahead of Baghdad."
1181#
1182# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
1183# In the past, some Kurdish nationalists, as a protest to the Iraqi
1184# Government, did not adhere to daylight saving time.  They referred
1185# to daylight saving as Saddam time.  But, as of today, the time zone
1186# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
1187#
1188# So we'll ignore the Economist's claim.

1220# Israel
1221
1222# From Ephraim Silverberg (2001-01-11):
1223#
1224# I coined "IST/IDT" circa 1988.  Until then there were three
1225# different abbreviations in use:
1226#
1227# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
1228# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
1229# EEST Eastern Europe Standard Time [used by almost everyone else]
1230#
1231# Since timezones should be called by country and not capital cities,
1232# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
1233# EEST was equally unacceptable.  Since "zonal" was not compatible with
1234# any other timezone abbreviation, I felt that 'IST' was the way to go
1235# and, indeed, it has received almost universal acceptance in timezone
1236# settings in Israeli computers.
1237#
1238# In any case, I am happy to share timezone abbreviations with India,
1239# high on my favorite-country list (and not only because my wife's
1240# family is from India).

1290# From Ephraim Silverberg
1291# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1292# and 2005-02-17):
1293
1294# According to the Office of the Secretary General of the Ministry of
1295# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1296# One thing is entrenched in law, however: that there must be at least 150
1297# days of daylight savings time annually.  From 1993-1998, the change to
1298# daylight savings time was on a Friday morning from midnight IST to
1299# 1 a.m IDT; up until 1998, the change back to standard time was on a
1300# Saturday night from midnight daylight savings time to 11 p.m. standard
1301# time.  1996 is an exception to this rule where the change back to standard
1302# time took place on Sunday night instead of Saturday night to avoid
1303# conflicts with the Jewish New Year.  In 1999, the change to
1304# daylight savings time was still on a Friday morning but from
1305# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1306# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1307# 1999 only.  In the year 2000, the change to daylight savings time was
1308# similar to 1999, but although the change back will be on a Friday, it
1309# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
1310# changes to/from will take place at 1 a.m. old time, but now there is no
1311# rule as to what day of the week it will take place in as the start date
1312# (except in 2003) is the night after the Passover Seder (i.e. the eve
1313# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1314# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
1315# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1402# to generate the transitions from 2005 through 2012.
1403# (I replaced "lastFri" with "Fri>=26" by hand.)
1404# The spring transitions all correspond to the following Rule:

1407#
1408# but older zic implementations (e.g., Solaris 8) do not support
1409# "Fri>=26" to mean April 1 in years like 2005, so for now we list the

1451
1452# From Paul Eggert (1995-03-06):
1453# Today's _Asahi Evening News_ (page 4) reports that Japan had
1454# daylight saving between 1948 and 1951, but "the system was discontinued
1455# because the public believed it would lead to longer working hours."
1456
1457# From Mayumi Negishi in the 2005-08-10 Japan Times:
1458# http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm
1459# Occupation authorities imposed daylight-saving time on Japan on
1460# [1948-05-01]....  But lack of prior debate and the execution of
1461# daylight-saving time just three days after the bill was passed generated
1462# deep hatred of the concept....  The Diet unceremoniously passed a bill to
1463# dump the unpopular system in October 1951, less than a month after the San
1464# Francisco Peace Treaty was signed.  (A government poll in 1951 showed 53%
1465# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
1466# wanted to keep it.)

1480# From Hideyuki Suzuki (1998-11-09):
1481# 'Tokyo' usually stands for the former location of Tokyo Astronomical
1482# Observatory: 139° 44' 40.90" E (9h 18m 58.727s), 35° 39' 16.0" N.

1486# The law is enacted on 1886-07-07.
1487
1488# From Hideyuki Suzuki (1998-11-16):
1489# The ordinance No. 51 (1886) established "standard time" in Japan,
1490# which stands for the time on 135° E.
1491# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1492# standard time".  And the same ordinance also established "western standard
1493# time", which stands for the time on 120° E....  But "western standard
1494# time" was abolished in the ordinance No. 529 (1937).  In the ordinance No.
1495# 167, there is no mention regarding for what place western standard time is
1496# standard....
1497#
1498# I wrote "ordinance" above, but I don't know how to translate.
1499# In Japanese it's "chokurei", which means ordinance from emperor.

1526# Winter time starts today Thursday, 30 September. Clocks will be turned back
1527# by one hour.  This is the latest government decision and it's final!
1528# The decision was taken because of the increase in working hours in

1619# From Kazakhstan Embassy's News Bulletin No. 11
1620# <http://www.kazsociety.org.uk/news/2005/03/30.htm> (2005-03-21):
1621# The Government of Kazakhstan passed a resolution March 15 abolishing
1622# daylight saving time citing lack of economic benefits and health
1623# complications coupled with a decrease in productivity.
1624#
1625# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1626# ... what happened was that the former Kazakhstan Eastern time zone
1627# was "blended" with the Central zone.  Therefore, Kazakhstan now has
1628# two time zones, and difference between them is one hour.  The zone
1629# closer to UTC is the former Western zone (probably still called the
1630# same), encompassing four provinces in the west: Aqtöbe, Atyraū,
1631# Mangghystaū, and West Kazakhstan.  The other zone encompasses
1632# everything else....  I guess that would make Kazakhstan time zones
1633# de jure UTC+5 and UTC+6 respectively.
1634
1635# From Stepan Golosunov (2016-03-27):
1636# Review of the linked documents from http://adilet.zan.kz/
1637# produced the following data for post-1991 Kazakhstan:
1638#
1639# 0. Act of the Cabinet of Ministers of the USSR
1640# from 1991-02-04 No. 20
1641# http://pravo.gov.ru/proxy/ips/?docbody=&nd=102010545
1642# removed the extra hour ("decree time") on the territory of the USSR
1643# starting with the last Sunday of March 1991.
1644# It also allowed (but not mandated) Kazakh SSR, Kirghiz SSR, Tajik SSR,
1645# Turkmen SSR and Uzbek SSR to not have "summer" time.
1646#
1647# The 1992-01-13 act also refers to the act of the Cabinet of Ministers
1648# of the Kazakh SSR from 1991-03-20 No. 170 "About the act of the Cabinet
1649# of Ministers of the USSR from 1991-02-04 No. 20" but I didn't found its
1650# text.
1651#
1652# According to Izvestia newspaper No. 68 (23334) from 1991-03-20
1653# (page 6; available at http://libinfo.org/newsr/newsr2574.djvu via
1654# http://libinfo.org/index.php?id=58564) on 1991-03-31 at 2:00 during
1655# transition to "summer" time:
1656# Republic of Georgia, Latvian SSR, Lithuanian SSR, SSR Moldova,
1657# Estonian SSR; Komi ASSR; Kaliningrad oblast; Nenets autonomous okrug
1658# were to move clocks 1 hour forward.
1659# Kazakh SSR (excluding Uralsk oblast); Republic of Kyrgyzstan, Tajik
1660# SSR; Andijan, Jizzakh, Namangan, Sirdarya, Tashkent, Fergana oblasts
1661# of the Uzbek SSR were to move clocks 1 hour backwards.
1662# Other territories were to not move clocks.
1663# When the "summer" time would end on 1991-09-29, clocks were to be
1664# moved 1 hour backwards on the territory of the USSR excluding
1665# Kazakhstan, Kirghizia, Uzbekistan, Turkmenia, Tajikistan.
1666#
1667# Apparently there were last minute changes. Apparently Kazakh act No. 170
1668# was one of such changes.
1669#
1670# https://ru.wikipedia.org/wiki/Декретное время
1671# claims that Sovetskaya Rossiya newspaper on 1991-03-29 published that
1672# Nenets autonomous okrug, Komi and Kazakhstan (excluding Uralsk oblast)
1673# were to not move clocks and Uralsk oblast was to move clocks
1674# forward; on 1991-09-29 Kazakhstan was to move clocks backwards.
1675# (Probably there were changes even after that publication. There is an
1676# article claiming that Kaliningrad oblast decided on 1991-03-29 to not
1677# move clocks.)
1678#
1679# This implies that on 1991-03-31 Asia/Oral remained on +04/+05 while
1680# the rest of Kazakhstan switched from +06/+07 to +05/06 or from +05/06
1681# to +04/+05. It's unclear how Qyzylorda oblast moved into the fifth
1682# time belt. (By switching from +04/+05 to +05/+06 on 1991-09-29?) ...

1686# http://adilet.zan.kz/rus/docs/P920000028_
1687# (text includes modification from the 1996 act)
1688# introduced new rules for calculation of time, mirroring Russian
1689# 1992-01-08 act.  It specified that time would be calculated
1690# according to time belts plus extra hour ("decree time"), moved clocks
1691# on the whole territory of Kazakhstan 1 hour forward on 1992-01-19 at
1692# 2:00, specified DST rules.  It acknowledged that Kazakhstan was
1693# located in the fourth and the fifth time belts and specified the
1694# border between them to be located east of Qostanay and Aktyubinsk
1695# oblasts (notably including Turgai and Qyzylorda oblasts into the fifth
1696# time belt).
1697#
1698# This means switch on 1992-01-19 at 2:00 from +04/+05 to +05/+06 for
1699# Asia/Aqtau, Asia/Aqtobe, Asia/Oral, Atyraū and Qostanay oblasts; from

1735# replaces the previous five documents.
1736#
1737# The only changes I noticed are in definition of the border between the
1738# fourth and the fifth time belts.  They account for changes in spelling
1739# and administrative division (splitting of Turgai oblast in 1997
1740# probably changed time in territories incorporated into Qostanay oblast
1741# (including Arkalyk) from +06/+07 to +05/+06) and move Qyzylorda oblast
1742# from being in the fifth time belt and not using decree time into the
1743# fourth time belt (no change in practice).

2091# (2005-03) both say that it has just one.
2092
2093# From Oscar van Vlijmen (1999-12-11):
2094# General Information Mongolia
2095# <http://www.mongoliatourism.gov.mn/general.htm> (1999-09)
2096# "Time: Mongolia has two time zones. Three westernmost provinces of
2097# Bayan-Ölgii, Uvs, and Hovd are one hour earlier than the capital city, and
2098# the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus
2099# eight hours."
2100
2101# From Rives McDow (1999-12-13):
2102# Mongolia discontinued the use of daylight savings time in 1999; 1998
2103# being the last year it was implemented.  The dates of implementation I am
2104# unsure of, but most probably it was similar to Russia, except for the time
2105# of implementation may have been different....
2106# Some maps in the past have indicated that there was an additional time
2107# zone in the eastern part of Mongolia, including the provinces of Dornod,
2108# Sükhbaatar, and possibly Khentii.
2109
2110# From Paul Eggert (1999-12-15):
2111# Naming and spelling is tricky in Mongolia.
2112# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
2113# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
2114# and sometimes Jirgalanta (with variant spellings), but the name Hovd
2115# is good enough for our purposes.
2116
2117# From Rives McDow (2001-05-13):
2118# In addition to Mongolia starting daylight savings as reported earlier
2119# (adopted DST on 2001-04-27 02:00 local time, ending 2001-09-28),

2126#
2127# [The province of Selenge is omitted from the above lists.]
2128

2180# direction, while Ulaanbaatar-Khovd takes 2 hours in the Eastern
2181# direction and 3:35 back, which indicates that Ulaanbaatar and Khovd are
2182# in different time zones (like we know about), while Choibalsan and

2401# Palestine
2402
2403# From Amos Shapir (1998-02-15):
2404#
2405# From 1917 until 1948-05-15, all of Palestine, including the parts now
2406# known as the Gaza Strip and the West Bank, was under British rule.
2407# Therefore the rules given for Israel for that period, apply there too...
2408#
2409# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
2410# (except a short occupation by Israel from 1956-11 till 1957-03, but no
2411# time zone was affected then).  It was never formally annexed to Egypt,
2412# though.
2413#
2414# The rest of Palestine was under Jordanian rule at that time, formally
2415# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
2416# the country's previous name of "the Hashemite Kingdom of the
2417# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
2418# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
2419# East Jerusalem.
2420#
2421# Both areas were occupied by Israel in June 1967, but not annexed (except
2422# for East Jerusalem).  They were on Israel time since then; there might
2423# have been a Military Governor's order about time zones, but I'm not aware
2424# of any (such orders may have been issued semi-annually whenever summer
2425# time was in effect, but maybe the legal aspect of time was just neglected).
2426#
2427# The Palestinian Authority was established in 1993, and got hold of most
2428# towns in the West Bank and Gaza by 1995.  I know that in order to
2429# demonstrate...independence, they have been switching to
2430# summer time and back on a different schedule than Israel's, but I don't
2431# know when this was started, or what algorithm is used (most likely the
2432# Jordanian one).
2433#
2434# To summarize, the table should probably look something like that:
2435#
2436# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
2437# ------------+-----------+-----------+-----------+-----------
2438# Israel      | Zion      | Zion      | Zion      | Zion
2439# West bank   | Zion      | Jordan    | Zion      | Jordan
2440# Gaza        | Zion      | Egypt     | Zion      | Jordan
2441#
2442# I guess more info may be available from the PA's web page (if/when they
2443# have one).
2444
2445# From Paul Eggert (2006-03-22):
2446# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
2447# with Shapir and assume that it observed DST from 1940 through 1947,
2448# and that it used Jordanian rules starting in 1996.
2449# We don't yet need a separate entry for the West Bank, since
2450# the only differences between it and Gaza that we know about
2451# occurred before our cutoff date of 1970.
2452# However, as we get more information, we may need to add entries
2453# for parts of the West Bank as they transitioned from Israel's rules
2454# to Palestine's rules.
2455
2456# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
2457# forwarded by Ephraim Silverberg:
2458#
2459# Despite the fact that Israel changed over to daylight savings time
2460# last week, the PLO Authority (PA) has decided not to turn its clocks
2461# one-hour forward at this time.  As a sign of independence from Israeli rule,
2462# the PA has decided to implement DST in April.
2463
2464# From Paul Eggert (1999-09-20):
2465# Daoud Kuttab writes in Holiday havoc
2466# http://www.jpost.com/com/Archive/22.Apr.1999/Opinion/Article-2.html
2467# (Jerusalem Post, 1999-04-22) that
2468# the Palestinian National Authority changed to DST on 1999-04-15.
2469# I vaguely recall that they switch back in October (sorry, forgot the source).
2470# For now, let's assume that the spring switch was at 24:00,
2471# and that they switch at 0:00 on the 3rd Fridays of April and October.
2472
2473# From Paul Eggert (2005-11-22):
2474# Starting 2004 transitions are from Steffen Thorsen's web site timeanddate.com.
2475
2476# From Steffen Thorsen (2005-11-23):
2477# A user from Gaza reported that Gaza made the change early because of
2478# the Ramadan.  Next year Ramadan will be even earlier, so I think
2479# there is a good chance next year's end date will be around two weeks
2480# earlier - the same goes for Jordan.
2481
2482# From Steffen Thorsen (2006-08-17):
2483# I was informed by a user in Bethlehem that in Bethlehem it started the
2484# same day as Israel, and after checking with other users in the area, I
2485# was informed that they started DST one day after Israel.  I was not
2486# able to find any authoritative sources at the time, nor details if
2487# Gaza changed as well, but presumed Gaza to follow the same rules as
2488# the West Bank.
2489
2490# From Steffen Thorsen (2006-09-26):
2491# according to the Palestine News Network (2006-09-19):
2492# http://english.pnn.ps/index.php?option=com_content&task=view&id=596&Itemid=5
2493# > The Council of Ministers announced that this year its winter schedule
2494# > will begin early, as of midnight Thursday.  It is also time to turn
2495# > back the clocks for winter.  Friday will begin an hour late this week.
2496# I guess it is likely that next year's date will be moved as well,
2497# because of the Ramadan.
2498
2499# From Jesper Nørgaard Welen (2007-09-18):
2500# According to Steffen Thorsen's web site the Gaza Strip and the rest of the
2501# Palestinian territories left DST early on 13.th. of September at 2:00.
2502
2503# From Paul Eggert (2007-09-20):
2504# My understanding is that Gaza and the West Bank disagree even over when
2505# the weekend is (Thursday+Friday versus Friday+Saturday), so I'd be a bit
2506# surprised if they agreed about DST.  But for now, assume they agree.
2507# For lack of better information, predict that future changes will be
2508# the 2nd Thursday of September at 02:00.
2509
2510# From Alexander Krivenyshev (2008-08-28):
2511# Here is an article, that Mideast running on different clocks at Ramadan.
2512#
2513# Gaza Strip (as Egypt) ended DST at midnight Thursday (Aug 28, 2008), while

2783# From Paul Eggert (2014-07-15):
2784# Time in Saudi Arabia and other countries in the Arabian peninsula was not
2785# standardized until relatively recently; we don't know when, and possibly it
2786# has never been made official.  Richard P Hunt, in "Islam city yielding to
2787# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
2788# observed standard time, and that people in Jeddah mostly observed quasi-solar
2789# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
2790# o'clock for "Arab" time).
2791#
2792# The TZ database cannot represent quasi-solar time; airline time is the best
2793# we can do.  The 1946 foreign air news digest of the U.S. Civil Aeronautics
2794# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated
2795# a weekly Dhahran-Cairo service, via the Saudi Arabian cities of Riyadh and
2796# Jidda, on March 14, 1947".  Shanks & Pottenger guessed 1950; go with the
2797# earlier date.
2798#
2799# Shanks & Pottenger also state that until 1968-05-01 Saudi Arabia had two
2800# time zones; the other zone, at UT +04, was in the far eastern part of
2801# the country.  Ignore this, as it's before our 1970 cutoff.

3101# From Paul Eggert (2014-10-04):
3102# Milne gives 7:16:56 for the meridian of Saigon in 1899, as being
3103# used in Lower Laos, Cambodia, and Annam.  But this is quite a ways
3104# from Saigon's location.  For now, ignore this and stick with Shanks
3105# and Pottenger for LMT before 1906.
3106
3107# From Arthur David Olson (2008-03-18):
3108# The English-language name of Vietnam's most populous city is "Ho Chi Minh
3109# City"; use Ho_Chi_Minh below to avoid a name of more than 14 characters.
3110
3111# From Paul Eggert (2014-10-21) after a heads-up from Trần Ngọc Quân:
3112# Trần Tiến Bình's authoritative book "Lịch Việt Nam: thế kỷ XX-XXI (1901-2100)"
3113# (Nhà xuất bản Văn Hoá - Thông Tin, Hanoi, 2005), pp 49-50,
3114# is quoted verbatim in:
3115# http://www.thoigian.com.vn/?mPage=P80D01
3116# is translated by Brian Inglis in:
3117# https://mm.icann.org/pipermail/tz/2014-October/021654.html
3118# and is the basis for the information below.
3119#
3120# The 1906 transition was effective July 1 and standardized Indochina to
3121# Phù Liễn Observatory, legally 104° 17' 17" east of Paris.
3122# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
3123# the Paris Meridian (2° 20' 14.03" E); the former yields 07:06:30.1333...
3124# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
3125# which is used below even though the modern-day Phù Liễn Observatory
3126# is closer to 07:06:31.  Abbreviate Phù Liễn Mean Time as PLMT.
3127#
3128# The following transitions occurred in Indochina in general (before 1954)
3129# and in South Vietnam in particular (after 1954):
3130# To 07:00 on 1911-05-01.
3131# To 08:00 on 1942-12-31 at 23:00.
3132# To 09:00 in 1945-03-14 at 23:00.
3133# To 07:00 on 1945-09-02 in Vietnam.
3134# To 08:00 on 1947-04-01 in French-controlled Indochina.
3135# To 07:00 on 1955-07-01 in South Vietnam.
3136# To 08:00 on 1959-12-31 at 23:00 in South Vietnam.
3137# To 07:00 on 1975-06-13 in South Vietnam.
