132386db68SMarcel Telka# Unless otherwise specified, the source for data through 1990 is:
142386db68SMarcel Telka# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
152386db68SMarcel Telka# San Diego: ACS Publications, Inc. (2003).
162386db68SMarcel Telka# Unfortunately this book contains many errors and cites no sources.
172386db68SMarcel Telka#
18a443617aSDan McDonald# Many years ago Gwillim Law wrote that a good source
19a443617aSDan McDonald# for time zone data was the International Air Transport
202386db68SMarcel Telka# Association's Standard Schedules Information Manual (IATA SSIM),
212386db68SMarcel Telka# published semiannually.  Law sent in several helpful summaries
222386db68SMarcel Telka# of the IATA's data after 1990.  Except where otherwise noted,
232386db68SMarcel Telka# IATA SSIM is the source for entries after 1990.
242386db68SMarcel Telka#
252386db68SMarcel Telka# Another source occasionally used is Edward W. Whitman, World Time Differences,
262386db68SMarcel Telka# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
272386db68SMarcel Telka# I found in the UCLA library.
282386db68SMarcel Telka#
292386db68SMarcel Telka# For data circa 1899, a common source is:

922386db68SMarcel Telka# Armenia
932386db68SMarcel Telka# From Paul Eggert (2006-03-22):
942386db68SMarcel Telka# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)
952386db68SMarcel Telka# in spring 1991, then to 4:00 with no DST in fall 1995, then
962386db68SMarcel Telka# readopting Russian DST in 1997.  Go with Shanks & Pottenger, even
972386db68SMarcel Telka# when they disagree with others.  Edgar Der-Danieliantz
982386db68SMarcel Telka# reported (1996-05-04) that Yerevan probably wouldn't use DST
992386db68SMarcel Telka# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that
1002386db68SMarcel Telka# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
1012386db68SMarcel Telka# but started switching at 3:00s in 1998.
1022386db68SMarcel Telka
1032386db68SMarcel Telka# From Arthur David Olson (2011-06-15):
1042386db68SMarcel Telka# While Russia abandoned DST in 2011, Armenia may choose to
1052386db68SMarcel Telka# follow Russia's "old" rules.

4042386db68SMarcel Telka# It says several things:
4052386db68SMarcel Telka#   * The Qing dynasty used local apparent solar time throughout China.
4062386db68SMarcel Telka#   * The Republic of China instituted Beijing mean solar time effective
4072386db68SMarcel Telka#     the official calendar book of 1914.
4082386db68SMarcel Telka#   * The French Concession in Shanghai set up signal stations in
4092386db68SMarcel Telka#     French docks in the 1890s, controlled by Xujiahui (Zikawei)
4102386db68SMarcel Telka#     Observatory and set to local mean time.
4112386db68SMarcel Telka#   * "From the end of the 19th century" it changed to UT+8.
4122386db68SMarcel Telka#   * Chinese Customs (by then reduced to a tool of foreign powers)
4132386db68SMarcel Telka#     eventually standardized on this time for all ports, and it
4142386db68SMarcel Telka#     became used by railways as well.
4152386db68SMarcel Telka#   * In 1918 the Central Observatory proposed dividing China into
4162386db68SMarcel Telka#     five time zones (see below for details).  This caught on
4172386db68SMarcel Telka#     at first only in coastal areas observing UT+8.
4182386db68SMarcel Telka#   * During WWII all of China was in theory was at UT+7.  In practice
4192386db68SMarcel Telka#     this was ignored in the west, and I presume was ignored in
4202386db68SMarcel Telka#     Japanese-occupied territory.
4212386db68SMarcel Telka#   * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
4222386db68SMarcel Telka#   * The five-zone plan was resurrected after WWII and officially put into
4232386db68SMarcel Telka#     place (with some modifications) in March 1948.  It's not clear
4242386db68SMarcel Telka#     how well it was observed in areas under Nationalist control.
4252386db68SMarcel Telka#   * The People's Liberation Army used UT+8 during the civil war.

4772386db68SMarcel Telka# From Luther Ma (2009-10-17):
4782386db68SMarcel Telka# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
4792386db68SMarcel Telka# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
4802386db68SMarcel Telka# but have no need of it. All planes, trains, and schools function on
4812386db68SMarcel Telka# what is called "Beijing time." When Han make an appointment in Chinese
4822386db68SMarcel Telka# they implicitly use Beijing time.
4832386db68SMarcel Telka#
4842386db68SMarcel Telka# On the other hand, ethnic Uyghurs, who make up about half the
4852386db68SMarcel Telka# population of Xinjiang, typically use "Xinjiang time" which is two
4862386db68SMarcel Telka# hours behind Beijing time, or UT +06. The government of the Xinjiang
4872386db68SMarcel Telka# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
4882386db68SMarcel Telka# local governments such as the Ürümqi city government use both times in
4892386db68SMarcel Telka# publications, referring to what is popularly called Xinjiang time as
4902386db68SMarcel Telka# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language
4912386db68SMarcel Telka# they almost invariably use Xinjiang time.
4922386db68SMarcel Telka#
4932386db68SMarcel Telka# (Their ethnic Han compatriots would typically have no clue of its
4942386db68SMarcel Telka# widespread use, however, because so extremely few of them are fluent in

4962386db68SMarcel Telka#
4972386db68SMarcel Telka# (...As with the rest of China there was a brief interval ending in 1990
4982386db68SMarcel Telka# or 1991 when summer time was in use.  The confusion was severe, with
4992386db68SMarcel Telka# the province not having dual times but four times in use at the same
5002386db68SMarcel Telka# time. Some areas remained on standard Xinjiang time or Beijing time and
5012386db68SMarcel Telka# others moving their clocks ahead.)

5032386db68SMarcel Telka# From Luther Ma (2009-11-19):
5042386db68SMarcel Telka# With the risk of being redundant to previous answers these are the most common
5052386db68SMarcel Telka# English "transliterations" (w/o using non-English symbols):
5062386db68SMarcel Telka#
5072386db68SMarcel Telka# 1. Wulumuqi...
5082386db68SMarcel Telka# 2. Kashi...
5092386db68SMarcel Telka# 3. Urumqi...
5102386db68SMarcel Telka# 4. Kashgar...
5112386db68SMarcel Telka# ...
5122386db68SMarcel Telka# 5. It seems that Uyghurs in Ürümqi has been using Xinjiang since at least the
5132386db68SMarcel Telka# 1960's. I know of one Han, now over 50, who grew up in the surrounding
5142386db68SMarcel Telka# countryside and used Xinjiang time as a child.
5152386db68SMarcel Telka#
5162386db68SMarcel Telka# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
5172386db68SMarcel Telka# start date for Xinjiang time.
5182386db68SMarcel Telka#
5192386db68SMarcel Telka# Without having access to local historical records, nor the ability to legally
5202386db68SMarcel Telka# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
5212386db68SMarcel Telka# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
5222386db68SMarcel Telka# not be using Beijing time, but some local time.)

5282386db68SMarcel Telka# From Luther Ma (2014-04-22):
5292386db68SMarcel Telka# I have interviewed numerous people of various nationalities and from
5302386db68SMarcel Telka# different localities in Xinjiang and can confirm the information in Guo's
5312386db68SMarcel Telka# report regarding Xinjiang, as well as the Time article reference by David
5322386db68SMarcel Telka# Cochrane.  Whether officially recognized or not (and both are officially
5332386db68SMarcel Telka# recognized), two separate times have been in use in Xinjiang since at least
5342386db68SMarcel Telka# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time;
5352386db68SMarcel Telka# and Beijing Time.  There is no confusion in Xinjiang as to which name refers
5362386db68SMarcel Telka# to which time. Both are widely used in the province, although in some
5372386db68SMarcel Telka# population groups might be use one to the exclusion of the other.  The only
5382386db68SMarcel Telka# problem is that computers and smart phones list Ürümqi (or Kashgar) as
5392386db68SMarcel Telka# having the same time as Beijing.

5412386db68SMarcel Telka# From Paul Eggert (2014-06-30):
5422386db68SMarcel Telka# In the early days of the PRC, Tibet was given its own time zone (UT +06)
5432386db68SMarcel Telka# but this was withdrawn in 1959 and never reinstated; see Tubten Khétsun,
5442386db68SMarcel Telka# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN
5452386db68SMarcel Telka# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x.
5462386db68SMarcel Telka# As this is before our 1970 cutoff, Tibet doesn't need a separate zone.
5472386db68SMarcel Telka#
5482386db68SMarcel Telka# Xinjiang Time is well-documented as being officially recognized.  E.g., see
5492386db68SMarcel Telka# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government"
5502386db68SMarcel Telka# <http://www.sinkiang.gov.cn/service/ourworking/> (2014-04-22).
5512386db68SMarcel Telka# Unfortunately, we have no good records of time in Xinjiang before 1986.
5522386db68SMarcel Telka# During the 20th century parts of Xinjiang were ruled by the Qing dynasty,
5532386db68SMarcel Telka# the Republic of China, various warlords, the First and Second East Turkestan
5542386db68SMarcel Telka# Republics, the Soviet Union, the Kuomintang, and the People's Republic of
5552386db68SMarcel Telka# China, and tracking down all these organizations' timekeeping rules would be
5562386db68SMarcel Telka# quite a trick.  Approximate this lost history by a transition from LMT to
5572386db68SMarcel Telka# UT +06 at the start of 1928, the year of accession of the warlord Jin Shuren,
5582386db68SMarcel Telka# which happens to be the date given by Shanks & Pottenger (no doubt as a
5592386db68SMarcel Telka# guess) as the transition from LMT.  Ignore the usage of +08 before
5602386db68SMarcel Telka# 1986-02-01 under the theory that the transition date to +08 is unknown and
5612386db68SMarcel Telka# that the sort of users who prefer Asia/Urumqi now typically ignored the
5622386db68SMarcel Telka# +08 mandate back then.

5792386db68SMarcel Telka# From Lee Yiu Chung (2009-10-24):
5802386db68SMarcel Telka# I found there are some mistakes for the...DST rule for Hong
5812386db68SMarcel Telka# Kong. [According] to the DST record from Hong Kong Observatory (actually,
5822386db68SMarcel Telka# it is not [an] observatory, but the official meteorological agency of HK,
5832386db68SMarcel Telka# and also serves as the official timing agency), there are some missing
5842386db68SMarcel Telka# and incorrect rules. Although the exact switch over time is missing, I

6752386db68SMarcel Telka
6762386db68SMarcel Telka# From Yu-Cheng Chuang (2013-07-12):
6772386db68SMarcel Telka# On Dec 28, 1895, the Meiji Emperor announced Ordinance No. 167 of
6782386db68SMarcel Telka# Meiji Year 28 "The clause about standard time", mentioned that
6792386db68SMarcel Telka# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
6802386db68SMarcel Telka# (both in Okinawa) adopt the Western Standard Time which is based on
6812386db68SMarcel Telka# 120E. The adoption began from Jan 1, 1896. The original text can be
6822386db68SMarcel Telka# found on Wikisource:
683f34ea95cSYuri Pankov# https://ja.wikisource.org/wiki/標準時ニ關スル件_(公布時)
6842386db68SMarcel Telka# ... This could be the first adoption of time zone in Taiwan, because
6852386db68SMarcel Telka# during the Qing Dynasty, it seems that there was no time zone
6862386db68SMarcel Telka# declared officially.
6872386db68SMarcel Telka#
6882386db68SMarcel Telka# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
6892386db68SMarcel Telka# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
6902386db68SMarcel Telka# revision in the ordinance No. 167 of Meiji year 28 about standard

6992386db68SMarcel Telka
7002386db68SMarcel Telka# From Yu-Cheng Chuang (2014-07-02):
7012cadd18dSYuri Pankov# I've found more evidence about when the time zone was switched from UT+9
7022cadd18dSYuri Pankov# back to UT+8 after WW2.  I believe it was on Sep 21, 1945.  In a document
7032386db68SMarcel Telka# during Japanese era [1] in which the officer told the staff to change time
7042cadd18dSYuri Pankov# zone back to Western Standard Time (UT+8) on Sep 21.  And in another
7052386db68SMarcel Telka# history page of National Cheng Kung University [2], on Sep 21 there is a
7062386db68SMarcel Telka# note "from today, switch back to Western Standard Time".  From these two
7072386db68SMarcel Telka# materials, I believe that the time zone change happened on Sep 21.  And
7082386db68SMarcel Telka# today I have found another monthly journal called "The Astronomical Herald"
7092386db68SMarcel Telka# from The Astronomical Society of Japan [3] in which it mentioned the fact
7102386db68SMarcel Telka# that:
7112386db68SMarcel Telka#
7122386db68SMarcel Telka# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
7132386db68SMarcel Telka# the time at 135E (GMT+9)
7142386db68SMarcel Telka#
7152386db68SMarcel Telka# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
7162386db68SMarcel Telka# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
7172386db68SMarcel Telka# as well as Yaeyama and Miyako islands, adopted a new time zone called
7182386db68SMarcel Telka# Western Standard Time, which is in GMT+8.
7192386db68SMarcel Telka#
7202386db68SMarcel Telka# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
7212386db68SMarcel Telka# territories of Japan adopted the same time zone, which is Central Standard
7222386db68SMarcel Telka# Time.

7352386db68SMarcel Telka# [It] abolishes Bulletin No. 207 in Showa 12 years (1937), which is a local
7362386db68SMarcel Telka# bulletin in Taiwan for that Ordinance No. 529. It also mentioned that 1am on
7372386db68SMarcel Telka# Sep 21, 1945 will be 12am on Sep 21.  I think this bulletin is much more
7382386db68SMarcel Telka# official than the one I mentioned in my first mail, because it's from the
7392386db68SMarcel Telka# top-level government in Taiwan. If you're going to quote any resource, this
7402386db68SMarcel Telka# would be a good one.

12242386db68SMarcel Telka# From Roozbeh Pournader (2005-04-05):
12252386db68SMarcel Telka# The text of the Iranian law, in effect since 1925, clearly mentions
12262386db68SMarcel Telka# that the true solar year is the measure, and there is no arithmetic
12272386db68SMarcel Telka# leap year calculation involved.  There has never been any serious

12302386db68SMarcel Telka# From Paul Eggert (2006-03-22):
12312386db68SMarcel Telka# Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
12322386db68SMarcel Telka# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
12332386db68SMarcel Telka# stopping after 2037 when 32-bit time_t's overflow.
12342386db68SMarcel Telka# That cal-persia used Birashk's approximation, which disagrees with the solar
12352386db68SMarcel Telka# calendar predictions for the year 2025, so I corrected those dates by hand.
12362386db68SMarcel Telka#
12372386db68SMarcel Telka# From Oscar van Vlijmen (2005-03-30), writing about future
12382386db68SMarcel Telka# discrepancies between cal-persia and the Iranian calendar:
12392386db68SMarcel Telka# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
12402386db68SMarcel Telka# the vernal equinox and that gets so close to 12:00 some local
12412386db68SMarcel Telka# Iranian time that the definition of the correct location needs to be
12422386db68SMarcel Telka# known exactly, amongst other factors.  2157 is even closer:
12432386db68SMarcel Telka# 2157-03-20 08:37:15.5 UT.  But the Gregorian year 2025 should give
12442386db68SMarcel Telka# no interpretation problem whatsoever.  By the way, another instant
12452386db68SMarcel Telka# in the near future where there will be a discrepancy between
12462386db68SMarcel Telka# arithmetical and astronomical Iranian calendars will be in 2058:
12472386db68SMarcel Telka# vernal equinox on 2058-03-20 09:03:05.9 UT.  The Java version of
12482386db68SMarcel Telka# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
12492386db68SMarcel Telka# 2058-03-21 for 1 Farvardin 1437 (astronomical).

13392386db68SMarcel Telka# "The three northern provinces ... switched their clocks this spring and
13402386db68SMarcel Telka# are an hour ahead of Baghdad."
13412386db68SMarcel Telka#
13422386db68SMarcel Telka# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
13432386db68SMarcel Telka# In the past, some Kurdish nationalists, as a protest to the Iraqi
13442386db68SMarcel Telka# Government, did not adhere to daylight saving time.  They referred
13452386db68SMarcel Telka# to daylight saving as Saddam time.  But, as of today, the time zone
13462386db68SMarcel Telka# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
13472386db68SMarcel Telka#

13912386db68SMarcel Telka# Since timezones should be called by country and not capital cities,
13922386db68SMarcel Telka# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
13932386db68SMarcel Telka# EEST was equally unacceptable.  Since "zonal" was not compatible with
13942386db68SMarcel Telka# any other timezone abbreviation, I felt that 'IST' was the way to go
13952386db68SMarcel Telka# and, indeed, it has received almost universal acceptance in timezone
13962386db68SMarcel Telka# settings in Israeli computers.
13972386db68SMarcel Telka#
13982386db68SMarcel Telka# In any case, I am happy to share timezone abbreviations with India,
13992386db68SMarcel Telka# high on my favorite-country list (and not only because my wife's
14002386db68SMarcel Telka# family is from India).

14502386db68SMarcel Telka# From Ephraim Silverberg
14512386db68SMarcel Telka# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
14522386db68SMarcel Telka# and 2005-02-17):
14532386db68SMarcel Telka
14542386db68SMarcel Telka# According to the Office of the Secretary General of the Ministry of
14552386db68SMarcel Telka# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
14562386db68SMarcel Telka# One thing is entrenched in law, however: that there must be at least 150
14572386db68SMarcel Telka# days of daylight savings time annually.  From 1993-1998, the change to
14582386db68SMarcel Telka# daylight savings time was on a Friday morning from midnight IST to
14592386db68SMarcel Telka# 1 a.m IDT; up until 1998, the change back to standard time was on a
14602386db68SMarcel Telka# Saturday night from midnight daylight savings time to 11 p.m. standard
14612386db68SMarcel Telka# time.  1996 is an exception to this rule where the change back to standard
14622386db68SMarcel Telka# time took place on Sunday night instead of Saturday night to avoid
14632386db68SMarcel Telka# conflicts with the Jewish New Year.  In 1999, the change to
14642386db68SMarcel Telka# daylight savings time was still on a Friday morning but from
14652386db68SMarcel Telka# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
14662386db68SMarcel Telka# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
14672386db68SMarcel Telka# 1999 only.  In the year 2000, the change to daylight savings time was
14682386db68SMarcel Telka# similar to 1999, but although the change back will be on a Friday, it
14692386db68SMarcel Telka# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
14702386db68SMarcel Telka# changes to/from will take place at 1 a.m. old time, but now there is no
14712386db68SMarcel Telka# rule as to what day of the week it will take place in as the start date
14722386db68SMarcel Telka# (except in 2003) is the night after the Passover Seder (i.e. the eve
14732386db68SMarcel Telka# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
14742386db68SMarcel Telka# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
14752386db68SMarcel Telka# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

16132386db68SMarcel Telka# Today's _Asahi Evening News_ (page 4) reports that Japan had
16142386db68SMarcel Telka# daylight saving between 1948 and 1951, but "the system was discontinued
16152386db68SMarcel Telka# because the public believed it would lead to longer working hours."

16192386db68SMarcel Telka# Occupation authorities imposed daylight-saving time on Japan on
16202386db68SMarcel Telka# [1948-05-01]....  But lack of prior debate and the execution of
16212386db68SMarcel Telka# daylight-saving time just three days after the bill was passed generated
16222386db68SMarcel Telka# deep hatred of the concept....  The Diet unceremoniously passed a bill to
16232386db68SMarcel Telka# dump the unpopular system in October 1951, less than a month after the San
16242386db68SMarcel Telka# Francisco Peace Treaty was signed.  (A government poll in 1951 showed 53%
16252386db68SMarcel Telka# of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
16262386db68SMarcel Telka# wanted to keep it.)

18372386db68SMarcel Telka# Estonian SSR; Komi ASSR; Kaliningrad oblast; Nenets autonomous okrug

18412386db68SMarcel Telka# of the Uzbek SSR were to move clocks 1 hour backwards.
18422386db68SMarcel Telka# Other territories were to not move clocks.

18462386db68SMarcel Telka#
18472386db68SMarcel Telka# Apparently there were last minute changes. Apparently Kazakh act No. 170

18502386db68SMarcel Telka# https://ru.wikipedia.org/wiki/Декретное время
18512386db68SMarcel Telka# claims that Sovetskaya Rossiya newspaper on 1991-03-29 published that
18522386db68SMarcel Telka# Nenets autonomous okrug, Komi and Kazakhstan (excluding Uralsk oblast)
18532386db68SMarcel Telka# were to not move clocks and Uralsk oblast was to move clocks
18542386db68SMarcel Telka# forward; on 1991-09-29 Kazakhstan was to move clocks backwards.
18552386db68SMarcel Telka# (Probably there were changes even after that publication. There is an
18562386db68SMarcel Telka# article claiming that Kaliningrad oblast decided on 1991-03-29 to not

18582386db68SMarcel Telka#

18602386db68SMarcel Telka# the rest of Kazakhstan switched from +06/+07 to +05/06 or from +05/06
1861a443617aSDan McDonald# to +04/+05. It's unclear how Qyzylorda oblast moved into the fifth

25852386db68SMarcel Telka# Palestine
25862386db68SMarcel Telka
25872386db68SMarcel Telka# From Amos Shapir (1998-02-15):
25882386db68SMarcel Telka#
25892386db68SMarcel Telka# From 1917 until 1948-05-15, all of Palestine, including the parts now
25902386db68SMarcel Telka# known as the Gaza Strip and the West Bank, was under British rule.
25912386db68SMarcel Telka# Therefore the rules given for Israel for that period, apply there too...
25922386db68SMarcel Telka#
25932386db68SMarcel Telka# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
25942386db68SMarcel Telka# (except a short occupation by Israel from 1956-11 till 1957-03, but no
25952386db68SMarcel Telka# time zone was affected then).  It was never formally annexed to Egypt,
25962386db68SMarcel Telka# though.
25972386db68SMarcel Telka#
25982386db68SMarcel Telka# The rest of Palestine was under Jordanian rule at that time, formally
25992386db68SMarcel Telka# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
26002386db68SMarcel Telka# the country's previous name of "the Hashemite Kingdom of the
26012386db68SMarcel Telka# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
26022386db68SMarcel Telka# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
26032386db68SMarcel Telka# East Jerusalem.
26042386db68SMarcel Telka#
26052386db68SMarcel Telka# Both areas were occupied by Israel in June 1967, but not annexed (except
26062386db68SMarcel Telka# for East Jerusalem).  They were on Israel time since then; there might
26072386db68SMarcel Telka# have been a Military Governor's order about time zones, but I'm not aware
26082386db68SMarcel Telka# of any (such orders may have been issued semi-annually whenever summer
26092386db68SMarcel Telka# time was in effect, but maybe the legal aspect of time was just neglected).
26102386db68SMarcel Telka#
26112386db68SMarcel Telka# The Palestinian Authority was established in 1993, and got hold of most
26122386db68SMarcel Telka# towns in the West Bank and Gaza by 1995.  I know that in order to
26132386db68SMarcel Telka# demonstrate...independence, they have been switching to
26142386db68SMarcel Telka# summer time and back on a different schedule than Israel's, but I don't
26152386db68SMarcel Telka# know when this was started, or what algorithm is used (most likely the
26162386db68SMarcel Telka# Jordanian one).
26172386db68SMarcel Telka#
26182386db68SMarcel Telka# To summarize, the table should probably look something like that:
26192386db68SMarcel Telka#
26202386db68SMarcel Telka# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-

26262386db68SMarcel Telka# I guess more info may be available from the PA's web page (if/when they
26272386db68SMarcel Telka# have one).

26292386db68SMarcel Telka# From Paul Eggert (2006-03-22):
26302386db68SMarcel Telka# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
26312386db68SMarcel Telka# with Shapir and assume that it observed DST from 1940 through 1947,
26322386db68SMarcel Telka# and that it used Jordanian rules starting in 1996.
26332386db68SMarcel Telka# We don't yet need a separate entry for the West Bank, since
26342386db68SMarcel Telka# the only differences between it and Gaza that we know about
26352386db68SMarcel Telka# occurred before our cutoff date of 1970.
26362386db68SMarcel Telka# However, as we get more information, we may need to add entries
26372386db68SMarcel Telka# for parts of the West Bank as they transitioned from Israel's rules
26382386db68SMarcel Telka# to Palestine's rules.

26422386db68SMarcel Telka#
26432386db68SMarcel Telka# Despite the fact that Israel changed over to daylight savings time
26442386db68SMarcel Telka# last week, the PLO Authority (PA) has decided not to turn its clocks
26452386db68SMarcel Telka# one-hour forward at this time.  As a sign of independence from Israeli rule,
26462386db68SMarcel Telka# the PA has decided to implement DST in April.

26522386db68SMarcel Telka# the Palestinian National Authority changed to DST on 1999-04-15.
26532386db68SMarcel Telka# I vaguely recall that they switch back in October (sorry, forgot the source).
26542386db68SMarcel Telka# For now, let's assume that the spring switch was at 24:00,
26552386db68SMarcel Telka# and that they switch at 0:00 on the 3rd Fridays of April and October.

26602386db68SMarcel Telka# From Steffen Thorsen (2005-11-23):
26612386db68SMarcel Telka# A user from Gaza reported that Gaza made the change early because of
26622386db68SMarcel Telka# the Ramadan.  Next year Ramadan will be even earlier, so I think
26632386db68SMarcel Telka# there is a good chance next year's end date will be around two weeks
26642386db68SMarcel Telka# earlier - the same goes for Jordan.
26652386db68SMarcel Telka
26662386db68SMarcel Telka# From Steffen Thorsen (2006-08-17):
26672386db68SMarcel Telka# I was informed by a user in Bethlehem that in Bethlehem it started the
26682386db68SMarcel Telka# same day as Israel, and after checking with other users in the area, I
26692386db68SMarcel Telka# was informed that they started DST one day after Israel.  I was not
26702386db68SMarcel Telka# able to find any authoritative sources at the time, nor details if
26712386db68SMarcel Telka# Gaza changed as well, but presumed Gaza to follow the same rules as
26722386db68SMarcel Telka# the West Bank.

26742386db68SMarcel Telka# From Steffen Thorsen (2006-09-26):

26802386db68SMarcel Telka# I guess it is likely that next year's date will be moved as well,

26872386db68SMarcel Telka# From Paul Eggert (2007-09-20):
26882386db68SMarcel Telka# My understanding is that Gaza and the West Bank disagree even over when
26892386db68SMarcel Telka# the weekend is (Thursday+Friday versus Friday+Saturday), so I'd be a bit
26902386db68SMarcel Telka# surprised if they agreed about DST.  But for now, assume they agree.

2983*4d6441a8SAndy Fiddaman# From Paul Eggert (2018-08-29):
29842386db68SMarcel Telka# Time in Saudi Arabia and other countries in the Arabian peninsula was not
2985*4d6441a8SAndy Fiddaman# standardized until 1968 or so; we don't know exactly when, and possibly it
29862386db68SMarcel Telka# has never been made official.  Richard P Hunt, in "Islam city yielding to
29872386db68SMarcel Telka# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
29882386db68SMarcel Telka# observed standard time, and that people in Jeddah mostly observed quasi-solar
29892386db68SMarcel Telka# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
29902386db68SMarcel Telka# o'clock for "Arab" time).
29912386db68SMarcel Telka#
2992*4d6441a8SAndy Fiddaman# Timekeeping differed depending on who you were and which part of Saudi
2993*4d6441a8SAndy Fiddaman# Arabia you were in.  In 1969, Elias Antar wrote that although a common
2994*4d6441a8SAndy Fiddaman# practice had been to set one's watch to 12:00 (i.e., midnight) at sunset -
2995*4d6441a8SAndy Fiddaman# which meant that the time on one side of a mountain could differ greatly from
2996*4d6441a8SAndy Fiddaman# the time on the other side - many foreigners set their watches to 6pm
2997*4d6441a8SAndy Fiddaman# instead, while airlines instead used UTC +03 (except in Dhahran, where they
2998*4d6441a8SAndy Fiddaman# used UTC +04), Aramco used UTC +03 with DST, and the Trans-Arabian Pipe Line
2999*4d6441a8SAndy Fiddaman# Company used Aramco time in eastern Saudi Arabia and airline time in western.
3000*4d6441a8SAndy Fiddaman# (The American Military Aid Advisory Group used plain UTC.)  Antar writes,
3001*4d6441a8SAndy Fiddaman# "A man named Higgins, so the story goes, used to run a local power
3002*4d6441a8SAndy Fiddaman# station. One day, the whole thing became too much for Higgins and he
3003*4d6441a8SAndy Fiddaman# assembled his staff and laid down the law. 'I've had enough of this,' he
3004*4d6441a8SAndy Fiddaman# shrieked. 'It is now 12 o'clock Higgins Time, and from now on this station is
3005*4d6441a8SAndy Fiddaman# going to run on Higgins Time.' And so, until last year, it did."  See:
3006*4d6441a8SAndy Fiddaman# Antar E. Dinner at When? Saudi Aramco World, 1969 March/April. 2-3.

3008*4d6441a8SAndy Fiddaman# newspapers.com says a similar story about Higgins was published in the Port
3009*4d6441a8SAndy Fiddaman# Angeles (WA) Evening News, 1965-03-10, page 5, but I lack access to the text.
3010*4d6441a8SAndy Fiddaman#
30112386db68SMarcel Telka# The TZ database cannot represent quasi-solar time; airline time is the best
30122386db68SMarcel Telka# we can do.  The 1946 foreign air news digest of the U.S. Civil Aeronautics
30132386db68SMarcel Telka# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated
30142386db68SMarcel Telka# a weekly Dhahran-Cairo service, via the Saudi Arabian cities of Riyadh and
30152386db68SMarcel Telka# Jidda, on March 14, 1947".  Shanks & Pottenger guessed 1950; go with the
30162386db68SMarcel Telka# earlier date.
30172386db68SMarcel Telka#
30182386db68SMarcel Telka# Shanks & Pottenger also state that until 1968-05-01 Saudi Arabia had two
30192386db68SMarcel Telka# time zones; the other zone, at UT +04, was in the far eastern part of
3020*4d6441a8SAndy Fiddaman# the country.  Presumably this is documenting airline time.  Ignore this,
3021*4d6441a8SAndy Fiddaman# as it's before our 1970 cutoff.

32002386db68SMarcel Telka# My best guess at a Syrian rule is "the Friday nearest April 1";

33392386db68SMarcel Telka#
33402386db68SMarcel Telka# The 1906 transition was effective July 1 and standardized Indochina to
3341006fe326SYuri Pankov# Phù Liễn Observatory, legally 104° 17' 17" east of Paris.
33422386db68SMarcel Telka# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
3343006fe326SYuri Pankov# the Paris Meridian (2° 20' 14.03" E); the former yields 07:06:30.1333...
33442386db68SMarcel Telka# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
33452386db68SMarcel Telka# which is used below even though the modern-day Phù Liễn Observatory
33462386db68SMarcel Telka# is closer to 07:06:31.  Abbreviate Phù Liễn Mean Time as PLMT.
33472386db68SMarcel Telka#
33482386db68SMarcel Telka# The following transitions occurred in Indochina in general (before 1954)
