11# From Paul Eggert (2018-06-19):
12#
13# Unless otherwise specified, the source for data through 1990 is:
14# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
15# San Diego: ACS Publications, Inc. (2003).
16# Unfortunately this book contains many errors and cites no sources.
17#
18# Many years ago Gwillim Law wrote that a good source
19# for time zone data was the International Air Transport
20# Association's Standard Schedules Information Manual (IATA SSIM),
21# published semiannually.  Law sent in several helpful summaries
22# of the IATA's data after 1990.  Except where otherwise noted,
23# IATA SSIM is the source for entries after 1990.
24#
25# Another source occasionally used is Edward W. Whitman, World Time Differences,
26# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
27# I found in the UCLA library.
28#
29# For data circa 1899, a common source is:
30# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94.
31# https://www.jstor.org/stable/1774359
32#
33# For Russian data circa 1919, a source is:
34# Byalokoz EL. New Counting of Time in Russia since July 1, 1919.
35# (See the 'europe' file for a fuller citation.)
36#
37# A reliable and entertaining source about time zones is
38# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
39#
40# The following alphabetic abbreviations appear in these tables
41# (corrections are welcome):
42#	     std  dst
43#	     LMT	Local Mean Time
44#	2:00 EET  EEST	Eastern European Time
45#	2:00 IST  IDT	Israel
46#	5:30 IST	India
47#	7:00 WIB	west Indonesia (Waktu Indonesia Barat)
48#	8:00 WITA	central Indonesia (Waktu Indonesia Tengah)
49#	8:00 CST	China
50#	8:00 PST  PDT*	Philippine Standard Time
51#	8:30 KST  KDT	Korea when at +0830
52#	9:00 WIT	east Indonesia (Waktu Indonesia Timur)
53#	9:00 JST  JDT	Japan
54#	9:00 KST  KDT	Korea when at +09
55#	9:30 ACST	Australian Central Standard Time
56# *I invented the abbreviation PDT; see "Philippines" below.
57# Otherwise, these tables typically use numeric abbreviations like +03
58# and +0330 for integer hour and minute UT offsets.  Although earlier
59# editions invented alphabetic time zone abbreviations for every
60# offset, this did not reflect common practice.

92# Armenia
93# From Paul Eggert (2006-03-22):
94# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)
95# in spring 1991, then to 4:00 with no DST in fall 1995, then
96# readopting Russian DST in 1997.  Go with Shanks & Pottenger, even
97# when they disagree with others.  Edgar Der-Danieliantz
98# reported (1996-05-04) that Yerevan probably wouldn't use DST
99# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that
100# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
101# but started switching at 3:00s in 1998.
102
103# From Arthur David Olson (2011-06-15):
104# While Russia abandoned DST in 2011, Armenia may choose to
105# follow Russia's "old" rules.
106
107# From Alexander Krivenyshev (2012-02-10):
108# According to News Armenia, on Feb 9, 2012,
109# http://newsarmenia.ru/society/20120209/42609695.html
110#

391# It gives evidence that at the beginning of the PRC, Beijing time was
392# officially apparent solar time!  However, Guo also says that the
393# evidence is dubious, as the relevant institute of astronomy had not
394# been taken over by the PRC yet.  It's plausible that apparent solar
395# time was announced but never implemented, and that people continued
396# to use UT+8.  As the Shanghai radio station (and I presume the
397# observatory) was still under control of French missionaries, it
398# could well have ignored any such mandate.

403# [undated and unknown publication location]
404# It says several things:
405#   * The Qing dynasty used local apparent solar time throughout China.
406#   * The Republic of China instituted Beijing mean solar time effective
407#     the official calendar book of 1914.
408#   * The French Concession in Shanghai set up signal stations in
409#     French docks in the 1890s, controlled by Xujiahui (Zikawei)
410#     Observatory and set to local mean time.
411#   * "From the end of the 19th century" it changed to UT+8.
412#   * Chinese Customs (by then reduced to a tool of foreign powers)
413#     eventually standardized on this time for all ports, and it
414#     became used by railways as well.
415#   * In 1918 the Central Observatory proposed dividing China into
416#     five time zones (see below for details).  This caught on
417#     at first only in coastal areas observing UT+8.
418#   * During WWII all of China was in theory was at UT+7.  In practice
419#     this was ignored in the west, and I presume was ignored in
420#     Japanese-occupied territory.
421#   * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
422#   * The five-zone plan was resurrected after WWII and officially put into
423#     place (with some modifications) in March 1948.  It's not clear
424#     how well it was observed in areas under Nationalist control.
425#   * The People's Liberation Army used UT+8 during the civil war.

427# An AP article "Shanghai Internat'l Area Little Changed" in the
428# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is
429# different - the occupied districts going by Tokyo time, an hour
430# ahead of that prevailing in the rest of Shanghai."  Guess that the
431# Xujiahui Observatory was under French control and stuck with UT +08.
432#
433# In earlier versions of this file, China had many separate Zone entries, but
434# this was based on what were apparently incorrect data in Shanks & Pottenger.
435# This has now been simplified to the two entries Asia/Shanghai and
436# Asia/Urumqi, with the others being links for backward compatibility.
437# Proposed in 1918 and theoretically in effect until 1949 (although in practice
438# mainly observed in coastal areas), the five zones were:
439#
440# Changbai Time ("Long-white Time", Long-white = Heilongjiang area) UT +08:30
441# Now part of Asia/Shanghai; its pre-1970 times are not recorded here.
442# Heilongjiang (except Mohe county), Jilin
443#
444# Zhongyuan Time ("Central plain Time") UT +08
445# Now part of Asia/Shanghai.
446# most of China
447# Milne gives 8:05:43.2 for Xujiahui Observatory time; round to nearest.
448# Guo says Shanghai switched to UT +08 "from the end of the 19th century".
449#
450# Long-shu Time (probably as Long and Shu were two names of the area) UT +07
451# Now part of Asia/Shanghai; its pre-1970 times are not recorded here.
452# Guangxi, Guizhou, Hainan, Ningxia, Sichuan, Shaanxi, and Yunnan;
453# most of Gansu; west Inner Mongolia; east Qinghai; and the Guangdong
454# counties Deqing, Enping, Kaiping, Luoding, Taishan, Xinxing,
455# Yangchun, Yangjiang, Yu'nan, and Yunfu.
456#
457# Xin-zang Time ("Xinjiang-Tibet Time") UT +06
458# This region is now part of either Asia/Urumqi or Asia/Shanghai with
459# current boundaries uncertain; times before 1970 for areas that
460# disagree with Ürümqi or Shanghai are not recorded here.
461# The Gansu counties Aksay, Anxi, Dunhuang, Subei; west Qinghai;

476
477# From Luther Ma (2009-10-17):
478# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
479# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
480# but have no need of it. All planes, trains, and schools function on
481# what is called "Beijing time." When Han make an appointment in Chinese
482# they implicitly use Beijing time.
483#
484# On the other hand, ethnic Uyghurs, who make up about half the
485# population of Xinjiang, typically use "Xinjiang time" which is two
486# hours behind Beijing time, or UT +06. The government of the Xinjiang
487# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
488# local governments such as the Ürümqi city government use both times in
489# publications, referring to what is popularly called Xinjiang time as
490# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language
491# they almost invariably use Xinjiang time.
492#
493# (Their ethnic Han compatriots would typically have no clue of its
494# widespread use, however, because so extremely few of them are fluent in
495# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
496#
497# (...As with the rest of China there was a brief interval ending in 1990
498# or 1991 when summer time was in use.  The confusion was severe, with
499# the province not having dual times but four times in use at the same
500# time. Some areas remained on standard Xinjiang time or Beijing time and
501# others moving their clocks ahead.)
502
503# From Luther Ma (2009-11-19):
504# With the risk of being redundant to previous answers these are the most common
505# English "transliterations" (w/o using non-English symbols):
506#
507# 1. Wulumuqi...
508# 2. Kashi...
509# 3. Urumqi...
510# 4. Kashgar...
511# ...
512# 5. It seems that Uyghurs in Ürümqi has been using Xinjiang since at least the
513# 1960's. I know of one Han, now over 50, who grew up in the surrounding
514# countryside and used Xinjiang time as a child.
515#
516# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
517# start date for Xinjiang time.
518#
519# Without having access to local historical records, nor the ability to legally
520# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
521# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
522# not be using Beijing time, but some local time.)
523
524# From David Cochrane (2014-03-26):
525# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986:
526# https://content.time.com/time/magazine/article/0,9171,960684,00.html
527
528# From Luther Ma (2014-04-22):
529# I have interviewed numerous people of various nationalities and from
530# different localities in Xinjiang and can confirm the information in Guo's
531# report regarding Xinjiang, as well as the Time article reference by David
532# Cochrane.  Whether officially recognized or not (and both are officially
533# recognized), two separate times have been in use in Xinjiang since at least
534# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time;
535# and Beijing Time.  There is no confusion in Xinjiang as to which name refers
536# to which time. Both are widely used in the province, although in some
537# population groups might be use one to the exclusion of the other.  The only
538# problem is that computers and smart phones list Ürümqi (or Kashgar) as
539# having the same time as Beijing.
540
541# From Paul Eggert (2014-06-30):
542# In the early days of the PRC, Tibet was given its own time zone (UT +06)
543# but this was withdrawn in 1959 and never reinstated; see Tubten Khétsun,
544# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN
545# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x.
546# As this is before our 1970 cutoff, Tibet doesn't need a separate zone.
547#
548# Xinjiang Time is well-documented as being officially recognized.  E.g., see
549# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government"
550# <http://www.sinkiang.gov.cn/service/ourworking/> (2014-04-22).
551# Unfortunately, we have no good records of time in Xinjiang before 1986.
552# During the 20th century parts of Xinjiang were ruled by the Qing dynasty,
553# the Republic of China, various warlords, the First and Second East Turkestan
554# Republics, the Soviet Union, the Kuomintang, and the People's Republic of
555# China, and tracking down all these organizations' timekeeping rules would be
556# quite a trick.  Approximate this lost history by a transition from LMT to
557# UT +06 at the start of 1928, the year of accession of the warlord Jin Shuren,
558# which happens to be the date given by Shanks & Pottenger (no doubt as a
559# guess) as the transition from LMT.  Ignore the usage of +08 before
560# 1986-02-01 under the theory that the transition date to +08 is unknown and
561# that the sort of users who prefer Asia/Urumqi now typically ignored the
562# +08 mandate back then.

671# From smallufo (2010-04-03):
672# According to Taiwan's CWB [Central Weather Bureau],
673# http://www.cwb.gov.tw/V6/astronomy/cdata/summert.htm
674# Taipei has DST in 1979 between July 1st and Sep 30.
675
676# From Yu-Cheng Chuang (2013-07-12):
677# On Dec 28, 1895, the Meiji Emperor announced Ordinance No. 167 of
678# Meiji Year 28 "The clause about standard time", mentioned that
679# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
680# (both in Okinawa) adopt the Western Standard Time which is based on
681# 120E. The adoption began from Jan 1, 1896. The original text can be
682# found on Wikisource:
683# https://ja.wikisource.org/wiki/標準時ニ關スル件_(公布時)
684# ... This could be the first adoption of time zone in Taiwan, because
685# during the Qing Dynasty, it seems that there was no time zone
686# declared officially.
687#
688# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
689# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
690# revision in the ordinance No. 167 of Meiji year 28 about standard
691# time", in which abolished the adoption of Western Standard Time in
692# western islands (listed above), which means the whole Japan
693# territory, including later occupations, adopt Japan Central Time
694# (UT+9). The adoption began on Oct 1, 1937. The original text can
695# be found on Wikisource:
696# 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
697#
698# That is, the time zone of Taipei switched to UT+9 on Oct 1, 1937.
699
700# From Yu-Cheng Chuang (2014-07-02):
701# I've found more evidence about when the time zone was switched from UT+9
702# back to UT+8 after WW2.  I believe it was on Sep 21, 1945.  In a document
703# during Japanese era [1] in which the officer told the staff to change time
704# zone back to Western Standard Time (UT+8) on Sep 21.  And in another
705# history page of National Cheng Kung University [2], on Sep 21 there is a
706# note "from today, switch back to Western Standard Time".  From these two
707# materials, I believe that the time zone change happened on Sep 21.  And
708# today I have found another monthly journal called "The Astronomical Herald"
709# from The Astronomical Society of Japan [3] in which it mentioned the fact
710# that:
711#
712# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
713# the time at 135E (GMT+9)
714#
715# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
716# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
717# as well as Yaeyama and Miyako islands, adopted a new time zone called
718# Western Standard Time, which is in GMT+8.
719#
720# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
721# territories of Japan adopted the same time zone, which is Central Standard
722# Time.

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

744# From Yu-Cheng Chuang (2014-07-02):
745# In 1946, DST in Taiwan was from May 15 and ended on Sep 30. The info from
746# Central Weather Bureau website was not correct.

751#
752# In 1947, DST in Taiwan was expanded to Oct 31. There is a backup of that

756#
757# Here is a brief translation:
758#
759#   The Summer Time this year is adopted from midnight Apr 15 until Sep 20
760#   midnight. To save (energy?) consumption, we're expanding Summer Time
761#   adoption till Oct 31 midnight.
762#
763# The Central Weather Bureau website didn't mention that, however it can
764# be found from historical government announcement database.
765
766# From Paul Eggert (2014-07-03):
767# As per Yu-Cheng Chuang, say that Taiwan was at UT +09 from 1937-10-01
768# until 1945-09-21 at 01:00, overriding Shanks & Pottenger.
769# Likewise, use Yu-Cheng Chuang's data for DST in Taiwan.

798# * LegisMac
799#   http://legismac.safp.gov.mo/legismac/descqry/Descqry.jsf?lang=pt
800#   A database for searching titles of legal documents of Macau in
801#   Chinese and Portuguese.  The term "HORÁRIO DE VERÃO" can be used for
802#   searching decrees about summer time.
803# * Archives of Macao
804#   http://www.archives.gov.mo/en/bo/
805#   It contains images of old official gazettes.
806# * The Macao Meteorological and Geophysical Bureau have a page listing the
807#   summer time history.  But it is not complete and has some mistakes.
808#   http://www.smg.gov.mo/smg/geophysics/e_t_Summer%20Time.htm
809# Macau adopted GMT+8 on 30 Oct 1904 to follow Hong Kong.  Clocks were
810# advanced by 25 minutes and 50 seconds.  Which means the LMT used was
811# +7:34:10.  As stated in the "Portaria No. 204" dated 21 October 1904
812# and published in the Official Gazette on 29 October 1904.

980# From Paul Eggert (1994-11-19):
981# Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
982# an hour recently, due to a law proposed by Zurab Murvanidze,
983# an MP who went on a hunger strike for 11 days to force discussion about it!
984# We have no details, but we'll guess they didn't move the clocks back in fall.
985#
986# From Mathew Englander, quoting AP (1996-10-23 13:05-04):
987# Instead of putting back clocks at the end of October, Georgia
988# will stay on daylight savings time this winter to save energy,
989# President Eduard Shevardnadze decreed Wednesday.
990#
991# From the BBC via Joseph S. Myers (2004-06-27):
992#
993# Georgia moved closer to Western Europe on Sunday...  The former Soviet
994# republic has changed its time zone back to that of Moscow.  As a result it
995# is now just four hours ahead of Greenwich Mean Time, rather than five hours
996# ahead.  The switch was decreed by the pro-Western president of Georgia,
997# Mikheil Saakashvili, who said the change was partly prompted by the process
998# of integration into Europe.
999
1000# From Teimuraz Abashidze (2005-11-07):
1001# Government of Georgia ... decided to NOT CHANGE daylight savings time on

1003# Currently, we are in fact GMT +4:00, as before 30 October it was GMT
1004# +3:00.... The problem is, there is NO FORMAL LAW or governmental document
1005# about it.  As far as I can find, I was told, that there is no document,
1006# because we just DIDN'T ISSUE document about switching to winter time....

1060# From Ian P. Beacock, in "A brief history of (modern) time", The Atlantic
1061# https://www.theatlantic.com/technology/archive/2015/12/the-creation-of-modern-time/421419/
1062# (2015-12-22):
1063# In January 1906, several thousand cotton-mill workers rioted on the
1064# outskirts of Bombay....  They were protesting the proposed abolition of
1065# local time in favor of Indian Standard Time....  Journalists called this
1066# dispute the "Battle of the Clocks."  It lasted nearly half a century.
1067
1068# From Paul Eggert (2017-04-20):
1069# Good luck trying to nail down old timekeeping records in India.
1070# "... in the nineteenth century ... Madras Observatory took its magnetic
1071# measurements on Göttingen time, its meteorological measurements on Madras
1072# (local) time, dropped its time ball on Greenwich (ocean navigator's) time,
1073# and distributed civil (local time)." -- Bartky IR. Selling the true time:
1074# 19th-century timekeeping in america. Stanford U Press (2000), 247 note 19.
1075# "A more potent cause of resistance to the general adoption of the present
1076# standard time lies in the fact that it is Madras time.  The citizen of
1077# Bombay, proud of being 'primus in Indis' and of Calcutta, equally proud of
1078# his city being the Capital of India, and - for a part of the year - the Seat
1079# of the Supreme Government, alike look down on Madras, and refuse to change
1080# the time they are using, for that of what they regard as a benighted
1081# Presidency; while Madras, having for long given the standard time to the
1082# rest of India, would resist the adoption of any other Indian standard in its
1083# place." -- Oldham RD. On Time in India: a suggestion for its improvement.
1084# Proceedings of the Asiatic Society of Bengal (April 1899), 49-55.
1085#
1086# "In 1870 ... Madras time - 'now used by the telegraph and regulated from the
1087# only government observatory' - was suggested as a standard railway time,
1088# first to be adopted on the Great Indian Peninsular Railway (GIPR)....
1089# Calcutta, Bombay, and Karachi, were to be allowed to continue with their
1090# local time for civil purposes." - Prasad R. Tracks of Change: Railways and
1091# Everyday Life in Colonial India. Cambridge University Press (2016), 145.
1092#
1093# Reed S, Low F. The Indian Year Book 1936-37. Bennett, Coleman, pp 27-8.
1094# https://archive.org/details/in.ernet.dli.2015.282212
1095# This lists +052110 as Madras local time used in railways, and says that on
1096# 1906-01-01 railways and telegraphs in India switched to +0530.  Some
1097# municipalities retained their former time, and the time in Calcutta
1098# continued to depend on whether you were at the railway station or at
1099# government offices.  Government time was at +055320 (according to Shanks) or
1100# at +0554 (according to the Indian Year Book).  Railway time is more
1101# appropriate for our purposes, as it was better documented, it is what we do
1102# elsewhere (e.g., Europe/London before 1880), and after 1906 it was
1103# consistent in the region now identified by Asia/Kolkata.  So, use railway
1104# time for 1870-1941.  Shanks is our only (and dubious) source for the
1105# 1941-1945 data.

1127# From Gwillim Law (2001-05-28), overriding Shanks & Pottenger:
1128# http://www.sumatera-inc.com/go_to_invest/about_indonesia.asp#standtime
1129# says that Indonesia's time zones changed on 1988-01-01.  Looking at some
1130# time zone maps, I think that must refer to Western Borneo (Kalimantan Barat
1131# and Kalimantan Tengah) switching from UTC+8 to UTC+7.
1132#
1133# From Paul Eggert (2007-03-10):
1134# Here is another correction to Shanks & Pottenger.
1135# JohnTWB writes that Japanese forces did not surrender control in
1136# Indonesia until 1945-09-01 00:00 at the earliest (in Jakarta) and
1137# other formal surrender ceremonies were September 9, 11, and 13, plus
1138# September 12 for the regional surrender to Mountbatten in Singapore.
1139# These would be the earliest possible times for a change.
1140# Régimes horaires pour le monde entier, by Henri Le Corre, (Éditions
1141# Traditionnelles, 1987, Paris) says that Java and Madura switched
1142# from UT +09 to +07:30 on 1945-09-23, and gives 1944-09-01 for Jayapura
1143# (Hollandia).  For now, assume all Indonesian locations other than Jayapura
1144# switched on 1945-09-23.
1145#
1146# From Paul Eggert (2013-08-11):
1147# Normally the tz database uses English-language abbreviations, but in

1196# From Roozbeh Pournader (2003-03-15):
1197# This is an English translation of what I just found (originally in Persian).
1198# The Gregorian dates in brackets are mine:
1199#
1200#	Official Newspaper No. 13548-1370/6/25 [1991-09-16]
1201#	No. 16760/T233 H				1370/6/10 [1991-09-01]
1202#
1203#	The Rule About Change of the Official Time of the Country
1204#
1205#	The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
1206#	based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
1207#	of the Country's Organization for Official and Employment Affairs,
1208#	and referring to the law for equating the working hours of workers
1209#	and officers in the whole country dated 1359/4/23 [1980-07-14], and
1210#	for synchronizing the official times of the country, agreed that:
1211#
1212#	The official time of the country will should move forward one hour
1213#	at the 24[:00] hours of the first day of Farvardin and should return
1214#	to its previous state at the 24[:00] hours of the 30th day of
1215#	Shahrivar.
1216#
1217#	First Deputy to the President - Hassan Habibi
1218#
1219# From personal experience, that agrees with what has been followed
1220# for at least the last 5 years.  Before that, for a few years, the
1221# date used was the first Thursday night of Farvardin and the last
1222# Thursday night of Shahrivar, but I can't give exact dates....
1223#
1224# From Roozbeh Pournader (2005-04-05):
1225# The text of the Iranian law, in effect since 1925, clearly mentions
1226# that the true solar year is the measure, and there is no arithmetic
1227# leap year calculation involved.  There has never been any serious
1228# plan to change that law....
1229#
1230# From Paul Eggert (2006-03-22):
1231# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
1232# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
1233# stopping after 2037 when 32-bit time_t's overflow.
1234# That cal-persia used Birashk's approximation, which disagrees with the solar
1235# calendar predictions for the year 2025, so I corrected those dates by hand.
1236#
1237# From Oscar van Vlijmen (2005-03-30), writing about future
1238# discrepancies between cal-persia and the Iranian calendar:
1239# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
1240# the vernal equinox and that gets so close to 12:00 some local
1241# Iranian time that the definition of the correct location needs to be
1242# known exactly, amongst other factors.  2157 is even closer:
1243# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
1244# no interpretation problem whatsoever.  By the way, another instant
1245# in the near future where there will be a discrepancy between
1246# arithmetical and astronomical Iranian calendars will be in 2058:
1247# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
1248# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
1249# 2058-03-21 for 1 Farvardin 1437 (astronomical).
1250#
1251# From Steffen Thorsen (2006-03-22):
1252# Several of my users have reported that Iran will not observe DST anymore:
1253# http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
1254#
1255# From Reuters (2007-09-16), with a heads-up from Jesper Nørgaard Welen:
1256# ... the Guardian Council ... approved a law on Sunday to re-introduce
1257# daylight saving time ...
1258# https://uk.reuters.com/article/oilRpt/idUKBLA65048420070916
1259#
1260# From Roozbeh Pournader (2007-11-05):
1261# This is quoted from Official Gazette of the Islamic Republic of
1262# Iran, Volume 63, No. 18242, dated Tuesday 1386/6/24
1263# [2007-10-16]. I am doing the best translation I can:...
1264# The official time of the country will be moved forward for one hour
1265# on the 24 hours of the first day of the month of Farvardin and will
1266# be changed back to its previous state on the 24 hours of the

1336# From Jonathan Lennox (2000-06-12):
1337# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
1338# the U.S. edition) on the Iraqi Kurds contains a paragraph:
1339# "The three northern provinces ... switched their clocks this spring and
1340# are an hour ahead of Baghdad."
1341#
1342# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
1343# In the past, some Kurdish nationalists, as a protest to the Iraqi
1344# Government, did not adhere to daylight saving time.  They referred
1345# to daylight saving as Saddam time.  But, as of today, the time zone
1346# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
1347#

1382# From Ephraim Silverberg (2001-01-11):
1383#
1384# I coined "IST/IDT" circa 1988.  Until then there were three
1385# different abbreviations in use:
1386#
1387# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
1388# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
1389# EEST Eastern Europe Standard Time [used by almost everyone else]
1390#
1391# Since timezones should be called by country and not capital cities,
1392# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
1393# EEST was equally unacceptable.  Since "zonal" was not compatible with
1394# any other timezone abbreviation, I felt that 'IST' was the way to go
1395# and, indeed, it has received almost universal acceptance in timezone
1396# settings in Israeli computers.
1397#
1398# In any case, I am happy to share timezone abbreviations with India,
1399# high on my favorite-country list (and not only because my wife's
1400# family is from India).

1450# From Ephraim Silverberg
1451# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1452# and 2005-02-17):
1453
1454# According to the Office of the Secretary General of the Ministry of
1455# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1456# One thing is entrenched in law, however: that there must be at least 150
1457# days of daylight savings time annually.  From 1993-1998, the change to
1458# daylight savings time was on a Friday morning from midnight IST to
1459# 1 a.m IDT; up until 1998, the change back to standard time was on a
1460# Saturday night from midnight daylight savings time to 11 p.m. standard
1461# time.  1996 is an exception to this rule where the change back to standard
1462# time took place on Sunday night instead of Saturday night to avoid
1463# conflicts with the Jewish New Year.  In 1999, the change to
1464# daylight savings time was still on a Friday morning but from
1465# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1466# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1467# 1999 only.  In the year 2000, the change to daylight savings time was
1468# similar to 1999, but although the change back will be on a Friday, it
1469# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
1470# changes to/from will take place at 1 a.m. old time, but now there is no
1471# rule as to what day of the week it will take place in as the start date
1472# (except in 2003) is the night after the Passover Seder (i.e. the eve
1473# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1474# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
1475# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1706# Winter time starts today Thursday, 30 September. Clocks will be turned back

1708# The decision was taken because of the increase in working hours in

1798
1799# From Kazakhstan Embassy's News Bulletin No. 11
1800# <http://www.kazsociety.org.uk/news/2005/03/30.htm> (2005-03-21):
1801# The Government of Kazakhstan passed a resolution March 15 abolishing
1802# daylight saving time citing lack of economic benefits and health
1803# complications coupled with a decrease in productivity.
1804#
1805# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1806# ... what happened was that the former Kazakhstan Eastern time zone
1807# was "blended" with the Central zone.  Therefore, Kazakhstan now has
1808# two time zones, and difference between them is one hour.  The zone
1809# closer to UTC is the former Western zone (probably still called the
1810# same), encompassing four provinces in the west: Aqtöbe, Atyraū,
1811# Mangghystaū, and West Kazakhstan.  The other zone encompasses
1812# everything else....  I guess that would make Kazakhstan time zones
1813# de jure UTC+5 and UTC+6 respectively.
1814
1815# From Stepan Golosunov (2016-03-27):
1816# Review of the linked documents from http://adilet.zan.kz/
1817# produced the following data for post-1991 Kazakhstan:
1818#
1819# 0. Act of the Cabinet of Ministers of the USSR
1820# from 1991-02-04 No. 20
1821# http://pravo.gov.ru/proxy/ips/?docbody=&nd=102010545
1822# removed the extra hour ("decree time") on the territory of the USSR
1823# starting with the last Sunday of March 1991.
1824# It also allowed (but not mandated) Kazakh SSR, Kirghiz SSR, Tajik SSR,
1825# Turkmen SSR and Uzbek SSR to not have "summer" time.
1826#
1827# The 1992-01-13 act also refers to the act of the Cabinet of Ministers
1828# of the Kazakh SSR from 1991-03-20 No. 170 "About the act of the Cabinet
1829# of Ministers of the USSR from 1991-02-04 No. 20" but I didn't found its
1830# text.
1831#
1832# According to Izvestia newspaper No. 68 (23334) from 1991-03-20
1833# (page 6; available at http://libinfo.org/newsr/newsr2574.djvu via
1834# http://libinfo.org/index.php?id=58564) on 1991-03-31 at 2:00 during
1835# transition to "summer" time:
1836# Republic of Georgia, Latvian SSR, Lithuanian SSR, SSR Moldova,
1837# Estonian SSR; Komi ASSR; Kaliningrad oblast; Nenets autonomous okrug
1838# were to move clocks 1 hour forward.
1839# Kazakh SSR (excluding Uralsk oblast); Republic of Kyrgyzstan, Tajik
1840# SSR; Andijan, Jizzakh, Namangan, Sirdarya, Tashkent, Fergana oblasts
1841# of the Uzbek SSR were to move clocks 1 hour backwards.
1842# Other territories were to not move clocks.
1843# When the "summer" time would end on 1991-09-29, clocks were to be
1844# moved 1 hour backwards on the territory of the USSR excluding
1845# Kazakhstan, Kirghizia, Uzbekistan, Turkmenia, Tajikistan.
1846#
1847# Apparently there were last minute changes. Apparently Kazakh act No. 170
1848# was one of such changes.
1849#
1850# https://ru.wikipedia.org/wiki/Декретное время
1851# claims that Sovetskaya Rossiya newspaper on 1991-03-29 published that
1852# Nenets autonomous okrug, Komi and Kazakhstan (excluding Uralsk oblast)
1853# were to not move clocks and Uralsk oblast was to move clocks
1854# forward; on 1991-09-29 Kazakhstan was to move clocks backwards.
1855# (Probably there were changes even after that publication. There is an
1856# article claiming that Kaliningrad oblast decided on 1991-03-29 to not
1857# move clocks.)
1858#
1859# This implies that on 1991-03-31 Asia/Oral remained on +04/+05 while
1860# the rest of Kazakhstan switched from +06/+07 to +05/06 or from +05/06
1861# to +04/+05. It's unclear how Qyzylorda oblast moved into the fifth
1862# time belt. (By switching from +04/+05 to +05/+06 on 1991-09-29?) ...
1863#
1864# 1. Act of the Cabinet of Ministers of the Republic of Kazakhstan
1865# from 1992-01-13 No. 28
1866# http://adilet.zan.kz/rus/docs/P920000028_
1867# (text includes modification from the 1996 act)
1868# introduced new rules for calculation of time, mirroring Russian
1869# 1992-01-08 act.  It specified that time would be calculated
1870# according to time belts plus extra hour ("decree time"), moved clocks
1871# on the whole territory of Kazakhstan 1 hour forward on 1992-01-19 at
1872# 2:00, specified DST rules.  It acknowledged that Kazakhstan was
1873# located in the fourth and the fifth time belts and specified the
1874# border between them to be located east of Qostanay and Aktyubinsk
1875# oblasts (notably including Turgai and Qyzylorda oblasts into the fifth
1876# time belt).
1877#
1878# This means switch on 1992-01-19 at 2:00 from +04/+05 to +05/+06 for
1879# Asia/Aqtau, Asia/Aqtobe, Asia/Oral, Atyraū and Qostanay oblasts; from
1880# +05/+06 to +06/+07 for Asia/Almaty and Asia/Qyzylorda (and Arkalyk)....

1885# cancels extra hour ("decree time") for Uralsk and Qyzylorda oblasts
1886# since the last Sunday of March 1992, while keeping them in the fourth
1887# and the fifth time belts respectively.
1888#
1889# 3. Order of the Prime Minister of the Republic of Kazakhstan
1890# from 1994-09-23 No. 384
1891# http://adilet.zan.kz/rus/docs/R940000384_
1892# cancels the extra hour ("decree time") on the territory of Mangghystaū

1894# the territory would correspond to the third time belt as a
1895# result)....

1897# 4. Act of the Government of the Republic of Kazakhstan
1898# from 1996-05-08 No. 575
1899# http://adilet.zan.kz/rus/docs/P960000575_
1900# amends the 1992-01-13 act to end summer time in October instead

1907# last Sunday of March 1999 while retaining the oblast in the fourth
1908# time belt.
1909#
1910# This means change from +05/+06 to +04/+05....

1914# http://adilet.zan.kz/rus/archive/docs/P000001749_/23.11.2000
1915# replaces the previous five documents.
1916#
1917# The only changes I noticed are in definition of the border between the
1918# fourth and the fifth time belts.  They account for changes in spelling
1919# and administrative division (splitting of Turgai oblast in 1997
1920# probably changed time in territories incorporated into Qostanay oblast
1921# (including Arkalyk) from +06/+07 to +05/+06) and move Qyzylorda oblast
1922# from being in the fifth time belt and not using decree time into the
1923# fourth time belt (no change in practice).

1936# zones (+04/+05 and +06/+07).  The changes were to be implemented
1937# during DST transitions in 2004 and 2005 but the acts got radically
1938# amended before implementation happened.

1942# http://adilet.zan.kz/rus/docs/P040001059_
1943# modified the 2000-11-23 act to remove exceptions from the "decree time"

1968# From Stepan Golosunov (2016-11-08):

1973#
1974# [For Qostanay] http://www.ng.kz/gazeta/195/hranit/
1975# suggests that clocks were to be moved 40 minutes backwards on
1976# 1920-01-01 to the fourth time belt.  But I do not understand

2586
2587# From Amos Shapir (1998-02-15):
2588#
2589# From 1917 until 1948-05-15, all of Palestine, including the parts now
2590# known as the Gaza Strip and the West Bank, was under British rule.
2591# Therefore the rules given for Israel for that period, apply there too...
2592#
2593# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
2594# (except a short occupation by Israel from 1956-11 till 1957-03, but no
2595# time zone was affected then).  It was never formally annexed to Egypt,
2596# though.
2597#
2598# The rest of Palestine was under Jordanian rule at that time, formally
2599# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
2600# the country's previous name of "the Hashemite Kingdom of the
2601# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
2602# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
2603# East Jerusalem.
2604#
2605# Both areas were occupied by Israel in June 1967, but not annexed (except
2606# for East Jerusalem).  They were on Israel time since then; there might
2607# have been a Military Governor's order about time zones, but I'm not aware
2608# of any (such orders may have been issued semi-annually whenever summer
2609# time was in effect, but maybe the legal aspect of time was just neglected).
2610#
2611# The Palestinian Authority was established in 1993, and got hold of most
2612# towns in the West Bank and Gaza by 1995.  I know that in order to
2613# demonstrate...independence, they have been switching to
2614# summer time and back on a different schedule than Israel's, but I don't
2615# know when this was started, or what algorithm is used (most likely the
2616# Jordanian one).
2617#
2618# To summarize, the table should probably look something like that:
2619#
2620# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
2621# ------------+-----------+-----------+-----------+-----------
2622# Israel      | Zion      | Zion      | Zion      | Zion
2623# West bank   | Zion      | Jordan    | Zion      | Jordan
2624# Gaza        | Zion      | Egypt     | Zion      | Jordan
2625#

2627# have one).

2629# From Paul Eggert (2006-03-22):
2630# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
2631# with Shapir and assume that it observed DST from 1940 through 1947,
2632# and that it used Jordanian rules starting in 1996.
2633# We don't yet need a separate entry for the West Bank, since
2634# the only differences between it and Gaza that we know about
2635# occurred before our cutoff date of 1970.
2636# However, as we get more information, we may need to add entries
2637# for parts of the West Bank as they transitioned from Israel's rules
2638# to Palestine's rules.

2643# Despite the fact that Israel changed over to daylight savings time
2644# last week, the PLO Authority (PA) has decided not to turn its clocks

2981# Saudi Arabia
2982#
2983# From Paul Eggert (2018-08-29):
2984# Time in Saudi Arabia and other countries in the Arabian peninsula was not
2985# standardized until 1968 or so; we don't know exactly when, and possibly it
2986# has never been made official.  Richard P Hunt, in "Islam city yielding to
2987# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
2988# observed standard time, and that people in Jeddah mostly observed quasi-solar
2989# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
2990# o'clock for "Arab" time).
2991#
2992# Timekeeping differed depending on who you were and which part of Saudi
2993# Arabia you were in.  In 1969, Elias Antar wrote that although a common
2994# practice had been to set one's watch to 12:00 (i.e., midnight) at sunset -
2995# which meant that the time on one side of a mountain could differ greatly from
2996# the time on the other side - many foreigners set their watches to 6pm
2997# instead, while airlines instead used UTC +03 (except in Dhahran, where they
2998# used UTC +04), Aramco used UTC +03 with DST, and the Trans-Arabian Pipe Line
2999# Company used Aramco time in eastern Saudi Arabia and airline time in western.
3000# (The American Military Aid Advisory Group used plain UTC.)  Antar writes,
3001# "A man named Higgins, so the story goes, used to run a local power
3002# station. One day, the whole thing became too much for Higgins and he
3003# assembled his staff and laid down the law. 'I've had enough of this,' he
3004# shrieked. 'It is now 12 o'clock Higgins Time, and from now on this station is
3005# going to run on Higgins Time.' And so, until last year, it did."  See:
3006# Antar E. Dinner at When? Saudi Aramco World, 1969 March/April. 2-3.
3007# http://archive.aramcoworld.com/issue/196902/dinner.at.when.htm
3008# newspapers.com says a similar story about Higgins was published in the Port
3009# Angeles (WA) Evening News, 1965-03-10, page 5, but I lack access to the text.
3010#
3011# The TZ database cannot represent quasi-solar time; airline time is the best
3012# we can do.  The 1946 foreign air news digest of the U.S. Civil Aeronautics
3013# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated
3014# a weekly Dhahran-Cairo service, via the Saudi Arabian cities of Riyadh and
3015# Jidda, on March 14, 1947".  Shanks & Pottenger guessed 1950; go with the
3016# earlier date.
3017#
3018# Shanks & Pottenger also state that until 1968-05-01 Saudi Arabia had two
3019# time zones; the other zone, at UT +04, was in the far eastern part of
3020# the country.  Presumably this is documenting airline time.  Ignore this,
3021# as it's before our 1970 cutoff.

3050# mean time, 5h. 4m. 21.9s. F., was used."  But 5:04:21.9 differs considerably
3051# from Colombo's meridian 5:19:24, so for now ignore Milne and stick with
3052# Shanks and Pottenger.

3086# From Paul Eggert (2016-10-18):
3087# "SLST" seems to be reasonably recent and rarely-used outside time

3089# it in the International Business Times of India in February and
3090# March of this year when discussing cricket match times, but nothing
3091# since then (though there has been a lot of cricket) and nothing in
3092# other English-language news sources.  Our old abbreviation "LKT" is
3093# even worse.  For now, let's use a numeric abbreviation; we can
3094# switch to "SLST" if it catches on.

3339#
3340# The 1906 transition was effective July 1 and standardized Indochina to
3341# Phù Liễn Observatory, legally 104° 17' 17" east of Paris.
3342# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
3343# the Paris Meridian (2° 20' 14.03" E); the former yields 07:06:30.1333...
3344# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
3345# which is used below even though the modern-day Phù Liễn Observatory
