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# http://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).

38# The following alphabetic abbreviations appear in these tables:

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 UTC 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
98# From Arthur David Olson (2011-06-15):
99# While Russia abandoned DST in 2011, Armenia may choose to
100# follow Russia's "old" rules.

278# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
279# China is across 4 physical time zones, before Feb 1, 1986 only the

281# has two of 'em - Peking's and Ürümqi (named after the capital of

329# From Paul Eggert (2017-01-05):
330# Alois Treindl kindly sent me translations of the following two sources:
331#
332# (1)
333# Guo Qingsheng (National Time-Service Center, CAS, Xi'an 710600, China)
334# Beijing Time at the Beginning of the PRC
335# China Historical Materials of Science and Technology
336# (Zhongguo ke ji shi liao, 中国科技史料), Vol. 24, No. 1 (2003)
337# It gives evidence that at the beginning of the PRC, Beijing time was
338# officially apparent solar time!  However, Guo also says that the
339# evidence is dubious, as the relevant institute of astronomy had not
340# been taken over by the PRC yet.  It's plausible that apparent solar
341# time was announced but never implemented, and that people continued
342# to use UT+8.  As the Shanghai radio station (and I presume the
343# observatory) was still under control of French missionaries, it
344# could well have ignored any such mandate.
345#
346# (2)
347# Guo Qing-sheng (Shaanxi Astronomical Observatory, CAS, Xi'an 710600, China)
348# A Study on the Standard Time Changes for the Past 100 Years in China
349# [undated and unknown publication location]
350# It says several things:
351#   * The Qing dynasty used local apparent solar time throughout China.
352#   * The Republic of China instituted Beijing mean solar time effective
353#     the official calendar book of 1914.
354#   * The French Concession in Shanghai set up signal stations in
355#     French docks in the 1890s, controlled by Xujiahui (Zikawei)
356#     Observatory and set to local mean time.
357#   * "From the end of the 19th century" it changed to UT+8.
358#   * Chinese Customs (by then reduced to a tool of foreign powers)
359#     eventually standardized on this time for all ports, and it
360#     became used by railways as well.
361#   * In 1918 the Central Observatory proposed dividing China into
362#     five time zones (see below for details).  This caught on
363#     at first only in coastal areas observing UT+8.
364#   * During WWII all of China was in theory was at UT+7.  In practice
365#     this was ignored in the west, and I presume was ignored in
366#     Japanese-occupied territory.
367#   * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
368#   * The five-zone plan was resurrected after WWII and officially put into
369#     place (with some modifications) in March 1948.  It's not clear
370#     how well it was observed in areas under Nationalist control.
371#   * The People's Liberation Army used UT+8 during the civil war.
372#
373# An AP article "Shanghai Internat'l Area Little Changed" in the
374# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is
375# different - the occupied districts going by Tokyo time, an hour
376# ahead of that prevailing in the rest of Shanghai."  Guess that the
377# Xujiahui Observatory was under French control and stuck with UT +08.
378#
379# In earlier versions of this file, China had many separate Zone entries, but
380# this was based on what were apparently incorrect data in Shanks & Pottenger.
381# This has now been simplified to the two entries Asia/Shanghai and
382# Asia/Urumqi, with the others being links for backward compatibility.
383# Proposed in 1918 and theoretically in effect until 1949 (although in practice
384# mainly observed in coastal areas), the five zones were:
385#
386# Changbai Time ("Long-white Time", Long-white = Heilongjiang area) UT +08:30
387# Now part of Asia/Shanghai; its pre-1970 times are not recorded here.
388# Heilongjiang (except Mohe county), Jilin
389#
390# Zhongyuan Time ("Central plain Time") UT +08
391# Now part of Asia/Shanghai.
392# most of China
393# Milne gives 8:05:43.2 for Xujiahui Observatory time; round to nearest.
394# Guo says Shanghai switched to UT +08 "from the end of the 19th century".

423# From Luther Ma (2009-10-17):
424# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
425# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
426# but have no need of it. All planes, trains, and schools function on
427# what is called "Beijing time." When Han make an appointment in Chinese
428# they implicitly use Beijing time.
429#
430# On the other hand, ethnic Uyghurs, who make up about half the
431# population of Xinjiang, typically use "Xinjiang time" which is two
432# hours behind Beijing time, or UT +06. The government of the Xinjiang
433# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
434# local governments such as the Ürümqi city government use both times in
435# publications, referring to what is popularly called Xinjiang time as
436# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language
437# they almost invariably use Xinjiang time.
438#
439# (Their ethnic Han compatriots would typically have no clue of its
440# widespread use, however, because so extremely few of them are fluent in
441# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
442#
443# (...As with the rest of China there was a brief interval ending in 1990
444# or 1991 when summer time was in use.  The confusion was severe, with
445# the province not having dual times but four times in use at the same
446# time. Some areas remained on standard Xinjiang time or Beijing time and
447# others moving their clocks ahead.)
448
449# From Luther Ma (2009-11-19):
450# With the risk of being redundant to previous answers these are the most common
451# English "transliterations" (w/o using non-English symbols):
452#
453# 1. Wulumuqi...
454# 2. Kashi...
455# 3. Urumqi...
456# 4. Kashgar...
457# ...
458# 5. It seems that Uyghurs in Ürümqi has been using Xinjiang since at least the
459# 1960's. I know of one Han, now over 50, who grew up in the surrounding
460# countryside and used Xinjiang time as a child.
461#
462# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
463# start date for Xinjiang time.
464#
465# Without having access to local historical records, nor the ability to legally
466# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
467# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
468# not be using Beijing time, but some local time.)
469
470# From David Cochrane (2014-03-26):
471# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986:
472# http://content.time.com/time/magazine/article/0,9171,960684,00.html
473
474# From Luther Ma (2014-04-22):
475# I have interviewed numerous people of various nationalities and from
476# different localities in Xinjiang and can confirm the information in Guo's
477# report regarding Xinjiang, as well as the Time article reference by David
478# Cochrane.  Whether officially recognized or not (and both are officially
479# recognized), two separate times have been in use in Xinjiang since at least
480# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time;
481# and Beijing Time.  There is no confusion in Xinjiang as to which name refers
482# to which time. Both are widely used in the province, although in some
483# population groups might be use one to the exclusion of the other.  The only
484# problem is that computers and smart phones list Ürümqi (or Kashgar) as
485# having the same time as Beijing.
486
487# From Paul Eggert (2014-06-30):
488# In the early days of the PRC, Tibet was given its own time zone (UT +06)
489# but this was withdrawn in 1959 and never reinstated; see Tubten Khétsun,
490# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN
491# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x.
492# As this is before our 1970 cutoff, Tibet doesn't need a separate zone.
493#
494# Xinjiang Time is well-documented as being officially recognized.  E.g., see
495# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government"
496# <http://www.sinkiang.gov.cn/service/ourworking/> (2014-04-22).
497# Unfortunately, we have no good records of time in Xinjiang before 1986.
498# During the 20th century parts of Xinjiang were ruled by the Qing dynasty,
499# the Republic of China, various warlords, the First and Second East Turkestan
500# Republics, the Soviet Union, the Kuomintang, and the People's Republic of
501# China, and tracking down all these organizations' timekeeping rules would be
502# quite a trick.  Approximate this lost history by a transition from LMT to
503# UT +06 at the start of 1928, the year of accession of the warlord Jin Shuren,
504# which happens to be the date given by Shanks & Pottenger (no doubt as a
505# guess) as the transition from LMT.  Ignore the usage of +08 before
506# 1986-02-01 under the theory that the transition date to +08 is unknown and
507# that the sort of users who prefer Asia/Urumqi now typically ignored the
508# +08 mandate back then.

617# From smallufo (2010-04-03):
618# According to Taiwan's CWB [Central Weather Bureau],
619# http://www.cwb.gov.tw/V6/astronomy/cdata/summert.htm
620# Taipei has DST in 1979 between July 1st and Sep 30.
621
622# From Yu-Cheng Chuang (2013-07-12):
623# On Dec 28, 1895, the Meiji Emperor announced Ordinance No. 167 of
624# Meiji Year 28 "The clause about standard time", mentioned that
625# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
626# (both in Okinawa) adopt the Western Standard Time which is based on
627# 120E. The adoption began from Jan 1, 1896. The original text can be
628# found on Wikisource:
629# http://ja.wikisource.org/wiki/標準時ニ關スル件_(公布時)
630# ... This could be the first adoption of time zone in Taiwan, because
631# during the Qing Dynasty, it seems that there was no time zone
632# declared officially.
633#
634# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
635# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
636# revision in the ordinance No. 167 of Meiji year 28 about standard
637# time", in which abolished the adoption of Western Standard Time in
638# western islands (listed above), which means the whole Japan
639# territory, including later occupations, adopt Japan Central Time
640# (UTC+9). The adoption began on Oct 1, 1937. The original text can
641# be found on Wikisource:
642# http://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
643#
644# That is, the time zone of Taipei switched to UTC+9 on Oct 1, 1937.
645
646# From Yu-Cheng Chuang (2014-07-02):
647# I've found more evidence about when the time zone was switched from UTC+9
648# back to UTC+8 after WW2.  I believe it was on Sep 21, 1945.  In a document
649# during Japanese era [1] in which the officer told the staff to change time
650# zone back to Western Standard Time (UTC+8) on Sep 21.  And in another
651# history page of National Cheng Kung University [2], on Sep 21 there is a
652# note "from today, switch back to Western Standard Time".  From these two
653# materials, I believe that the time zone change happened on Sep 21.  And
654# today I have found another monthly journal called "The Astronomical Herald"
655# from The Astronomical Society of Japan [3] in which it mentioned the fact
656# that:
657#
658# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
659# the time at 135E (GMT+9)
660#
661# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
662# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
663# as well as Yaeyama and Miyako islands, adopted a new time zone called
664# Western Standard Time, which is in GMT+8.
665#
666# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
667# territories of Japan adopted the same time zone, which is Central Standard
668# Time.

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

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

697#

702#
703# Here is a brief translation:
704#
705#   The Summer Time this year is adopted from midnight Apr 15 until Sep 20
706#   midnight. To save (energy?) consumption, we're expanding Summer Time
707#   adoption till Oct 31 midnight.
708#
709# The Central Weather Bureau website didn't mention that, however it can
710# be found from historical government announcement database.
711
712# From Paul Eggert (2014-07-03):
713# As per Yu-Cheng Chuang, say that Taiwan was at UT +09 from 1937-10-01
714# until 1945-09-21 at 01:00, overriding Shanks & Pottenger.

802# From Paul Eggert (1994-11-19):
803# Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
804# an hour recently, due to a law proposed by Zurab Murvanidze,
805# an MP who went on a hunger strike for 11 days to force discussion about it!
806# We have no details, but we'll guess they didn't move the clocks back in fall.
807#
808# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
809# Instead of putting back clocks at the end of October, Georgia
810# will stay on daylight savings time this winter to save energy,
811# President Eduard Shevardnadze decreed Wednesday.
812#
813# From the BBC via Joseph S. Myers (2004-06-27):
814#
815# Georgia moved closer to Western Europe on Sunday...  The former Soviet
816# republic has changed its time zone back to that of Moscow.  As a result it
817# is now just four hours ahead of Greenwich Mean Time, rather than five hours
818# ahead.  The switch was decreed by the pro-Western president of Georgia,
819# Mikheil Saakashvili, who said the change was partly prompted by the process
820# of integration into Europe.
821
822# From Teimuraz Abashidze (2005-11-07):
823# Government of Georgia ... decided to NOT CHANGE daylight savings time on
824# [Oct.] 30, as it was done before during last more than 10 years.
825# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
826# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
827# about it.  As far as I can find, I was told, that there is no document,
828# because we just DIDN'T ISSUE document about switching to winter time....
829# I don't know what can be done, especially knowing that some years ago our
830# DST rules where changed THREE TIMES during one month.

854# East Timor may be late for its millennium
855# <http://etan.org/et99c/december/26-31/30ETMAY.htm> (1999-12-26/31):
856# Portugal tried to change the time forward in 1974 because the sun

858# Timorese and I still don't think it would work today because it

909# http://www.sumatera-inc.com/go_to_invest/about_indonesia.asp#standtime
910# says that Indonesia's time zones changed on 1988-01-01.  Looking at some

913#
914# From Paul Eggert (2007-03-10):
915# Here is another correction to Shanks & Pottenger.
916# JohnTWB writes that Japanese forces did not surrender control in
917# Indonesia until 1945-09-01 00:00 at the earliest (in Jakarta) and
918# other formal surrender ceremonies were September 9, 11, and 13, plus
919# September 12 for the regional surrender to Mountbatten in Singapore.
920# These would be the earliest possible times for a change.
921# Régimes horaires pour le monde entier, by Henri Le Corre, (Éditions
922# Traditionnelles, 1987, Paris) says that Java and Madura switched
923# from UT +09 to +07:30 on 1945-09-23, and gives 1944-09-01 for Jayapura
924# (Hollandia).  For now, assume all Indonesian locations other than Jayapura
925# switched on 1945-09-23.
926#
927# From Paul Eggert (2013-08-11):
928# Normally the tz database uses English-language abbreviations, but in

977# From Roozbeh Pournader (2003-03-15):
978# This is an English translation of what I just found (originally in Persian).
979# The Gregorian dates in brackets are mine:
980#
981#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
982#	No. 16760/T233 H				1370/6/10 [1991-09-01]
983#
984#	The Rule About Change of the Official Time of the Country
985#
986#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
987#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
988#	of the Country's Organization for Official and Employment Affairs,
989#	and referring to the law for equating the working hours of workers
990#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
991#	for synchronizing the official times of the country, agreed that:
992#
993#	The official time of the country will should move forward one hour
994#	at the 24[:00] hours of the first day of Farvardin and should return
995#	to its previous state at the 24[:00] hours of the 30th day of
996#	Shahrivar.
997#
998#	First Deputy to the President - Hassan Habibi
999#
1000# From personal experience, that agrees with what has been followed
1001# for at least the last 5 years.  Before that, for a few years, the
1002# date used was the first Thursday night of Farvardin and the last
1003# Thursday night of Shahrivar, but I can't give exact dates....
1004#
1005# From Roozbeh Pournader (2005-04-05):
1006# The text of the Iranian law, in effect since 1925, clearly mentions
1007# that the true solar year is the measure, and there is no arithmetic
1008# leap year calculation involved.  There has never been any serious
1009# plan to change that law....
1010#
1011# From Paul Eggert (2006-03-22):
1012# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
1013# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
1014# stopping after 2037 when 32-bit time_t's overflow.
1015# That cal-persia used Birashk's approximation, which disagrees with the solar
1016# calendar predictions for the year 2025, so I corrected those dates by hand.
1017#
1018# From Oscar van Vlijmen (2005-03-30), writing about future
1019# discrepancies between cal-persia and the Iranian calendar:
1020# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
1021# the vernal equinox and that gets so close to 12:00 some local
1022# Iranian time that the definition of the correct location needs to be
1023# known exactly, amongst other factors.  2157 is even closer:
1024# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
1025# no interpretation problem whatsoever.  By the way, another instant
1026# in the near future where there will be a discrepancy between
1027# arithmetical and astronomical Iranian calendars will be in 2058:
1028# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
1029# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
1030# 2058-03-21 for 1 Farvardin 1437 (astronomical).
1031#
1032# From Steffen Thorsen (2006-03-22):
1033# Several of my users have reported that Iran will not observe DST anymore:

1117# From Jonathan Lennox (2000-06-12):
1118# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
1119# the U.S. edition) on the Iraqi Kurds contains a paragraph:
1120# "The three northern provinces ... switched their clocks this spring and
1121# are an hour ahead of Baghdad."
1122#
1123# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
1124# In the past, some Kurdish nationalists, as a protest to the Iraqi
1125# Government, did not adhere to daylight saving time.  They referred
1126# to daylight saving as Saddam time.  But, as of today, the time zone
1127# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
1128#
1129# So we'll ignore the Economist's claim.

1163# From Ephraim Silverberg (2001-01-11):
1164#
1165# I coined "IST/IDT" circa 1988.  Until then there were three
1166# different abbreviations in use:
1167#
1168# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
1169# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
1170# EEST Eastern Europe Standard Time [used by almost everyone else]
1171#
1172# Since timezones should be called by country and not capital cities,
1173# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
1174# EEST was equally unacceptable.  Since "zonal" was not compatible with
1175# any other timezone abbreviation, I felt that 'IST' was the way to go
1176# and, indeed, it has received almost universal acceptance in timezone
1177# settings in Israeli computers.
1178#
1179# In any case, I am happy to share timezone abbreviations with India,
1180# high on my favorite-country list (and not only because my wife's
1181# family is from India).

1231# From Ephraim Silverberg
1232# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1233# and 2005-02-17):
1234
1235# According to the Office of the Secretary General of the Ministry of
1236# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1237# One thing is entrenched in law, however: that there must be at least 150
1238# days of daylight savings time annually.  From 1993-1998, the change to
1239# daylight savings time was on a Friday morning from midnight IST to
1240# 1 a.m IDT; up until 1998, the change back to standard time was on a
1241# Saturday night from midnight daylight savings time to 11 p.m. standard
1242# time.  1996 is an exception to this rule where the change back to standard
1243# time took place on Sunday night instead of Saturday night to avoid
1244# conflicts with the Jewish New Year.  In 1999, the change to
1245# daylight savings time was still on a Friday morning but from
1246# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1247# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1248# 1999 only.  In the year 2000, the change to daylight savings time was
1249# similar to 1999, but although the change back will be on a Friday, it
1250# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
1251# changes to/from will take place at 1 a.m. old time, but now there is no
1252# rule as to what day of the week it will take place in as the start date
1253# (except in 2003) is the night after the Passover Seder (i.e. the eve
1254# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1255# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
1256# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1392
1393# From Paul Eggert (1995-03-06):
1394# Today's _Asahi Evening News_ (page 4) reports that Japan had
1395# daylight saving between 1948 and 1951, but "the system was discontinued
1396# because the public believed it would lead to longer working hours."
1397
1398# From Mayumi Negishi in the 2005-08-10 Japan Times:
1399# http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm
1400# Occupation authorities imposed daylight-saving time on Japan on
1401# [1948-05-01]....  But lack of prior debate and the execution of
1402# daylight-saving time just three days after the bill was passed generated
1403# deep hatred of the concept....  The Diet unceremoniously passed a bill to
1404# dump the unpopular system in October 1951, less than a month after the San
1405# Francisco Peace Treaty was signed.  (A government poll in 1951 showed 53%
1406# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
1407# wanted to keep it.)
1408
1409# From Paul Eggert (2006-03-22):
1410# Shanks & Pottenger write that DST in Japan during those years was as follows:

1416# but the only locations using it (for birth certificates, presumably, since
1417# their audience is astrologers) were US military bases.  For now, assume
1418# that for most purposes daylight-saving time was observed; otherwise, what
1419# would have been the point of the 1951 poll?
1420
1421# From Hideyuki Suzuki (1998-11-09):
1422# 'Tokyo' usually stands for the former location of Tokyo Astronomical
1423# Observatory: 139 degrees 44' 40.90" E (9h 18m 58.727s),
1424# 35 degrees 39' 16.0" N.

1429
1430# From Hideyuki Suzuki (1998-11-16):
1431# The ordinance No. 51 (1886) established "standard time" in Japan,
1432# which stands for the time on 135 degrees E.
1433# In the ordinance No. 167 (1895), "standard time" was renamed to "central
1434# standard time".  And the same ordinance also established "western standard
1435# time", which stands for the time on 120 degrees E....  But "western standard
1436# time" was abolished in the ordinance No. 529 (1937).  In the ordinance No.
1437# 167, there is no mention regarding for what place western standard time is
1438# standard....
1439#
1440# I wrote "ordinance" above, but I don't know how to translate.
1441# In Japanese it's "chokurei", which means ordinance from emperor.

1561# From Kazakhstan Embassy's News Bulletin No. 11
1562# <http://www.kazsociety.org.uk/news/2005/03/30.htm> (2005-03-21):
1563# The Government of Kazakhstan passed a resolution March 15 abolishing
1564# daylight saving time citing lack of economic benefits and health
1565# complications coupled with a decrease in productivity.
1566#
1567# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1568# ... what happened was that the former Kazakhstan Eastern time zone
1569# was "blended" with the Central zone.  Therefore, Kazakhstan now has
1570# two time zones, and difference between them is one hour.  The zone
1571# closer to UTC is the former Western zone (probably still called the
1572# same), encompassing four provinces in the west: Aqtöbe, Atyraū,
1573# Mangghystaū, and West Kazakhstan.  The other zone encompasses
1574# everything else....  I guess that would make Kazakhstan time zones
1575# de jure UTC+5 and UTC+6 respectively.
1576
1577# From Stepan Golosunov (2016-03-27):
1578# Review of the linked documents from http://adilet.zan.kz/
1579# produced the following data for post-1991 Kazakhstan:
1580#
1581# 0. Act of the Cabinet of Ministers of the USSR
1582# from 1991-02-04 No. 20
1583# http://pravo.gov.ru/proxy/ips/?docbody=&nd=102010545
1584# removed the extra hour ("decree time") on the territory of the USSR
1585# starting with the last Sunday of March 1991.
1586# It also allowed (but not mandated) Kazakh SSR, Kirghiz SSR, Tajik SSR,
1587# Turkmen SSR and Uzbek SSR to not have "summer" time.
1588#
1589# The 1992-01-13 act also refers to the act of the Cabinet of Ministers
1590# of the Kazakh SSR from 1991-03-20 No. 170 "About the act of the Cabinet
1591# of Ministers of the USSR from 1991-02-04 No. 20" but I didn't found its
1592# text.
1593#
1594# According to Izvestia newspaper No. 68 (23334) from 1991-03-20
1595# (page 6; available at http://libinfo.org/newsr/newsr2574.djvu via
1596# http://libinfo.org/index.php?id=58564) on 1991-03-31 at 2:00 during
1597# transition to "summer" time:
1598# Republic of Georgia, Latvian SSR, Lithuanian SSR, SSR Moldova,
1599# Estonian SSR; Komi ASSR; Kaliningrad oblast; Nenets autonomous okrug
1600# were to move clocks 1 hour forward.
1601# Kazakh SSR (excluding Uralsk oblast); Republic of Kyrgyzstan, Tajik
1602# SSR; Andijan, Jizzakh, Namangan, Sirdarya, Tashkent, Fergana oblasts
1603# of the Uzbek SSR were to move clocks 1 hour backwards.
1604# Other territories were to not move clocks.
1605# When the "summer" time would end on 1991-09-29, clocks were to be
1606# moved 1 hour backwards on the territory of the USSR excluding
1607# Kazakhstan, Kirghizia, Uzbekistan, Turkmenia, Tajikistan.
1608#
1609# Apparently there were last minute changes. Apparently Kazakh act No. 170
1610# was one of such changes.
1611#
1612# https://ru.wikipedia.org/wiki/Декретное время
1613# claims that Sovetskaya Rossiya newspaper on 1991-03-29 published that
1614# Nenets autonomous okrug, Komi and Kazakhstan (excluding Uralsk oblast)
1615# were to not move clocks and Uralsk oblast was to move clocks
1616# forward; on 1991-09-29 Kazakhstan was to move clocks backwards.
1617# (Probably there were changes even after that publication. There is an
1618# article claiming that Kaliningrad oblast decided on 1991-03-29 to not
1619# move clocks.)
1620#
1621# This implies that on 1991-03-31 Asia/Oral remained on +04/+05 while
1622# the rest of Kazakhstan switched from +06/+07 to +05/06 or from +05/06
1623# to +04/+05. It's unclear how Qyzylorda oblast moved into the fifth
1624# time belt. (By switching from +04/+05 to +05/+06 on 1991-09-29?) ...

1629# (text includes modification from the 1996 act)
1630# introduced new rules for calculation of time, mirroring Russian
1631# 1992-01-08 act.  It specified that time would be calculated
1632# according to time belts plus extra hour ("decree time"), moved clocks
1633# on the whole territory of Kazakhstan 1 hour forward on 1992-01-19 at
1634# 2:00, specified DST rules.  It acknowledged that Kazakhstan was
1635# located in the fourth and the fifth time belts and specified the
1636# border between them to be located east of Qostanay and Aktyubinsk
1637# oblasts (notably including Turgai and Qyzylorda oblasts into the fifth
1638# time belt).
1639#
1640# This means switch on 1992-01-19 at 2:00 from +04/+05 to +05/+06 for
1641# Asia/Aqtau, Asia/Aqtobe, Asia/Oral, Atyraū and Qostanay oblasts; from

2039# Naming and spelling is tricky in Mongolia.
2040# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
2041# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
2042# and sometimes Jirgalanta (with variant spellings), but the name Hovd
2043# is good enough for our purposes.
2044
2045# From Rives McDow (2001-05-13):
2046# In addition to Mongolia starting daylight savings as reported earlier
2047# (adopted DST on 2001-04-27 02:00 local time, ending 2001-09-28),
2048# there are three time zones.

2054#
2055# [The province of Selenge is omitted from the above lists.]
2056
2057# From Ganbold Ts., Ulaanbaatar (2004-04-17):
2058# Daylight saving occurs at 02:00 local time last Saturday of March.
2059# It will change back to normal at 02:00 local time last Saturday of
2060# September.... As I remember this rule was changed in 2001.

2330
2331# From Amos Shapir (1998-02-15):
2332#
2333# From 1917 until 1948-05-15, all of Palestine, including the parts now
2334# known as the Gaza Strip and the West Bank, was under British rule.
2335# Therefore the rules given for Israel for that period, apply there too...
2336#
2337# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
2338# (except a short occupation by Israel from 1956-11 till 1957-03, but no
2339# time zone was affected then).  It was never formally annexed to Egypt,
2340# though.
2341#
2342# The rest of Palestine was under Jordanian rule at that time, formally
2343# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
2344# the country's previous name of "the Hashemite Kingdom of the
2345# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
2346# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
2347# East Jerusalem.
2348#
2349# Both areas were occupied by Israel in June 1967, but not annexed (except
2350# for East Jerusalem).  They were on Israel time since then; there might
2351# have been a Military Governor's order about time zones, but I'm not aware
2352# of any (such orders may have been issued semi-annually whenever summer
2353# time was in effect, but maybe the legal aspect of time was just neglected).
2354#
2355# The Palestinian Authority was established in 1993, and got hold of most
2356# towns in the West Bank and Gaza by 1995.  I know that in order to
2357# demonstrate...independence, they have been switching to
2358# summer time and back on a different schedule than Israel's, but I don't
2359# know when this was started, or what algorithm is used (most likely the
2360# Jordanian one).
2361#
2362# To summarize, the table should probably look something like that:
2363#
2364# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
2365# ------------+-----------+-----------+-----------+-----------
2366# Israel      | Zion      | Zion      | Zion      | Zion
2367# West bank   | Zion      | Jordan    | Zion      | Jordan
2368# Gaza        | Zion      | Egypt     | Zion      | Jordan

2376# and that it used Jordanian rules starting in 1996.
2377# We don't yet need a separate entry for the West Bank, since
2378# the only differences between it and Gaza that we know about
2379# occurred before our cutoff date of 1970.
2380# However, as we get more information, we may need to add entries
2381# for parts of the West Bank as they transitioned from Israel's rules

2406# the Ramadan.  Next year Ramadan will be even earlier, so I think
2407# there is a good chance next year's end date will be around two weeks
2408# earlier - the same goes for Jordan.
2409
2410# From Steffen Thorsen (2006-08-17):
2411# I was informed by a user in Bethlehem that in Bethlehem it started the
2412# same day as Israel, and after checking with other users in the area, I
2413# was informed that they started DST one day after Israel.  I was not
2414# able to find any authoritative sources at the time, nor details if
2415# Gaza changed as well, but presumed Gaza to follow the same rules as
2416# the West Bank.

2430
2431# From Paul Eggert (2007-09-20):
2432# My understanding is that Gaza and the West Bank disagree even over when

2434# surprised if they agreed about DST.  But for now, assume they agree.

2703#
2704# From Paul Eggert (2014-07-15):
2705# Time in Saudi Arabia and other countries in the Arabian peninsula was not
2706# standardized until relatively recently; we don't know when, and possibly it
2707# has never been made official.  Richard P Hunt, in "Islam city yielding to
2708# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
2709# observed standard time, and that people in Jeddah mostly observed quasi-solar
2710# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
2711# o'clock for "Arab" time).
2712#
2713# The TZ database cannot represent quasi-solar time; airline time is the best
2714# we can do.  The 1946 foreign air news digest of the U.S. Civil Aeronautics
2715# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated
2716# a weekly Dhahran-Cairo service, via the Saudi Arabian cities of Riyadh and
2717# Jidda, on March 14, 1947".  Shanks & Pottenger guessed 1950; go with the
2718# earlier date.
2719#
2720# Shanks & Pottenger also state that until 1968-05-01 Saudi Arabia had two
2721# time zones; the other zone, at UT +04, was in the far eastern part of
2722# the country.  Ignore this, as it's before our 1970 cutoff.

3038# http://mm.icann.org/pipermail/tz/2014-October/021654.html
3039# and is the basis for the information below.
3040#
3041# The 1906 transition was effective July 1 and standardized Indochina to
3042# Phù Liễn Observatory, legally 104 deg. 17'17" east of Paris.
3043# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
3044# the Paris Meridian (2 deg. 20'14.03" E); the former yields 07:06:30.1333...
3045# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
3046# which is used below even though the modern-day Phù Liễn Observatory
3047# is closer to 07:06:31.  Abbreviate Phù Liễn Mean Time as PLMT.
3048#
3049# The following transitions occurred in Indochina in general (before 1954)
3050# and in South Vietnam in particular (after 1954):
3051# To 07:00 on 1911-05-01.
