93158421Swollman# From Paul Eggert (2006-03-22):
94158421Swollman# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)

96158421Swollman# readopting Russian DST in 1997.  Go with Shanks & Pottenger, even
97158421Swollman# when they disagree with others.  Edgar Der-Danieliantz
98153670Swollman# reported (1996-05-04) that Yerevan probably wouldn't use DST
9943014Swollman# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that
10043014Swollman# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,

343273438Sdelphij# It gives evidence that at the beginning of the PRC, Beijing time was
344273438Sdelphij# officially apparent solar time!  However, Guo also says that the
345273438Sdelphij# evidence is dubious, as the relevant institute of astronomy had not
346273438Sdelphij# been taken over by the PRC yet.  It's plausible that apparent solar
347273438Sdelphij# time was announced but never implemented, and that people continued
348273438Sdelphij# to use UT+8.  As the Shanghai radio station (and I presume the

356273438Sdelphij# It says several things:
357273438Sdelphij#   * The Qing dynasty used local apparent solar time throughout China.
358273438Sdelphij#   * The Republic of China instituted Beijing mean solar time effective
359273438Sdelphij#     the official calendar book of 1914.
360273438Sdelphij#   * The French Concession in Shanghai set up signal stations in
361309568Sglebius#     French docks in the 1890s, controlled by Xujiahui (Zikawei)
362309568Sglebius#     Observatory and set to local mean time.
363273438Sdelphij#   * "From the end of the 19th century" it changed to UT+8.
364273438Sdelphij#   * Chinese Customs (by then reduced to a tool of foreign powers)
365273438Sdelphij#     eventually standardized on this time for all ports, and it
366273438Sdelphij#     became used by railways as well.
367273438Sdelphij#   * In 1918 the Central Observatory proposed dividing China into
368273438Sdelphij#     five time zones (see below for details).  This caught on
369273438Sdelphij#     at first only in coastal areas observing UT+8.
370273438Sdelphij#   * During WWII all of China was in theory was at UT+7.  In practice
371273438Sdelphij#     this was ignored in the west, and I presume was ignored in
372273438Sdelphij#     Japanese-occupied territory.
373273438Sdelphij#   * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
374273438Sdelphij#   * The five-zone plan was resurrected after WWII and officially put into
375273438Sdelphij#     place (with some modifications) in March 1948.  It's not clear
376273438Sdelphij#     how well it was observed in areas under Nationalist control.
377273438Sdelphij#   * The People's Liberation Army used UT+8 during the civil war.
378273438Sdelphij#
379273438Sdelphij# An AP article "Shanghai Internat'l Area Little Changed" in the

381273438Sdelphij# different - the occupied districts going by Tokyo time, an hour
382273438Sdelphij# ahead of that prevailing in the rest of Shanghai."  Guess that the
383309568Sglebius# Xujiahui Observatory was under French control and stuck with UT +08.
384273438Sdelphij#
385273438Sdelphij# In earlier versions of this file, China had many separate Zone entries, but
386309568Sglebius# this was based on what were apparently incorrect data in Shanks & Pottenger.
387273438Sdelphij# This has now been simplified to the two entries Asia/Shanghai and
388273438Sdelphij# Asia/Urumqi, with the others being links for backward compatibility.
389273438Sdelphij# Proposed in 1918 and theoretically in effect until 1949 (although in practice
390273438Sdelphij# mainly observed in coastal areas), the five zones were:
391273438Sdelphij#

430200835Sedwin
431200835Sedwin# From Luther Ma (2009-10-17):
432200835Sedwin# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
433200835Sedwin# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
434200835Sedwin# but have no need of it. All planes, trains, and schools function on
435200835Sedwin# what is called "Beijing time." When Han make an appointment in Chinese
436200835Sedwin# they implicitly use Beijing time.
437200835Sedwin#
438200835Sedwin# On the other hand, ethnic Uyghurs, who make up about half the
439200835Sedwin# population of Xinjiang, typically use "Xinjiang time" which is two
440309568Sglebius# hours behind Beijing time, or UT +06. The government of the Xinjiang
441200835Sedwin# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
442273438Sdelphij# local governments such as the ��r��mqi city government use both times in
443200835Sedwin# publications, referring to what is popularly called Xinjiang time as
444273438Sdelphij# "��r��mqi time." When Uyghurs make an appointment in the Uyghur language
445200835Sedwin# they almost invariably use Xinjiang time.
446200835Sedwin#
447200835Sedwin# (Their ethnic Han compatriots would typically have no clue of its
448200835Sedwin# widespread use, however, because so extremely few of them are fluent in
449200835Sedwin# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
450200835Sedwin#
451200835Sedwin# (...As with the rest of China there was a brief interval ending in 1990
452200835Sedwin# or 1991 when summer time was in use.  The confusion was severe, with
453200835Sedwin# the province not having dual times but four times in use at the same
454200835Sedwin# time. Some areas remained on standard Xinjiang time or Beijing time and
455200835Sedwin# others moving their clocks ahead.)
456200835Sedwin
457200835Sedwin# From Luther Ma (2009-11-19):
458200835Sedwin# With the risk of being redundant to previous answers these are the most common
459200835Sedwin# English "transliterations" (w/o using non-English symbols):
460200835Sedwin#
461200835Sedwin# 1. Wulumuqi...
462200835Sedwin# 2. Kashi...
463200835Sedwin# 3. Urumqi...
464200835Sedwin# 4. Kashgar...
465200835Sedwin# ...
466273438Sdelphij# 5. It seems that Uyghurs in ��r��mqi has been using Xinjiang since at least the
467200835Sedwin# 1960's. I know of one Han, now over 50, who grew up in the surrounding
468200835Sedwin# countryside and used Xinjiang time as a child.
469200835Sedwin#
470200835Sedwin# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any
471200835Sedwin# start date for Xinjiang time.
472200835Sedwin#
473200835Sedwin# Without having access to local historical records, nor the ability to legally
474200835Sedwin# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur
475200835Sedwin# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also
476200835Sedwin# not be using Beijing time, but some local time.)
477200835Sedwin
478273438Sdelphij# From David Cochrane (2014-03-26):

481273438Sdelphij
482273438Sdelphij# From Luther Ma (2014-04-22):
483273438Sdelphij# I have interviewed numerous people of various nationalities and from
484273438Sdelphij# different localities in Xinjiang and can confirm the information in Guo's
485273438Sdelphij# report regarding Xinjiang, as well as the Time article reference by David
486273438Sdelphij# Cochrane.  Whether officially recognized or not (and both are officially
487273438Sdelphij# recognized), two separate times have been in use in Xinjiang since at least
488273438Sdelphij# the Cultural Revolution: Xinjiang Time (XJT), aka ��r��mqi Time or local time;
489273438Sdelphij# and Beijing Time.  There is no confusion in Xinjiang as to which name refers
490273438Sdelphij# to which time. Both are widely used in the province, although in some
491273438Sdelphij# population groups might be use one to the exclusion of the other.  The only
492273438Sdelphij# problem is that computers and smart phones list ��r��mqi (or Kashgar) as
493273438Sdelphij# having the same time as Beijing.
494273438Sdelphij
495273438Sdelphij# From Paul Eggert (2014-06-30):
496309568Sglebius# In the early days of the PRC, Tibet was given its own time zone (UT +06)
497309568Sglebius# but this was withdrawn in 1959 and never reinstated; see Tubten Kh��tsun,
498273438Sdelphij# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN
499273438Sdelphij# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x.
500273438Sdelphij# As this is before our 1970 cutoff, Tibet doesn't need a separate zone.
501273438Sdelphij#
502273438Sdelphij# Xinjiang Time is well-documented as being officially recognized.  E.g., see
503273438Sdelphij# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government"
504273438Sdelphij# <http://www.sinkiang.gov.cn/service/ourworking/> (2014-04-22).
505273438Sdelphij# Unfortunately, we have no good records of time in Xinjiang before 1986.
506309568Sglebius# During the 20th century parts of Xinjiang were ruled by the Qing dynasty,
507273438Sdelphij# the Republic of China, various warlords, the First and Second East Turkestan
508273438Sdelphij# Republics, the Soviet Union, the Kuomintang, and the People's Republic of
509273438Sdelphij# China, and tracking down all these organizations' timekeeping rules would be
510273438Sdelphij# quite a trick.  Approximate this lost history by a transition from LMT to
511309568Sglebius# UT +06 at the start of 1928, the year of accession of the warlord Jin Shuren,
512273438Sdelphij# which happens to be the date given by Shanks & Pottenger (no doubt as a
513309568Sglebius# guess) as the transition from LMT.  Ignore the usage of +08 before
514309568Sglebius# 1986-02-01 under the theory that the transition date to +08 is unknown and
515273438Sdelphij# that the sort of users who prefer Asia/Urumqi now typically ignored the
516309568Sglebius# +08 mandate back then.

625206868Sedwin# From smallufo (2010-04-03):
626273438Sdelphij# According to Taiwan's CWB [Central Weather Bureau],
627206868Sedwin# http://www.cwb.gov.tw/V6/astronomy/cdata/summert.htm
628206868Sedwin# Taipei has DST in 1979 between July 1st and Sep 30.
629206868Sedwin
630273438Sdelphij# From Yu-Cheng Chuang (2013-07-12):
631273438Sdelphij# On Dec 28, 1895, the Meiji Emperor announced Ordinance No. 167 of
632273438Sdelphij# Meiji Year 28 "The clause about standard time", mentioned that
633273438Sdelphij# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
634273438Sdelphij# (both in Okinawa) adopt the Western Standard Time which is based on
635273438Sdelphij# 120E. The adoption began from Jan 1, 1896. The original text can be
636273438Sdelphij# found on Wikisource:
637273438Sdelphij# http://ja.wikisource.org/wiki/������������������������_(���������)
638273438Sdelphij# ... This could be the first adoption of time zone in Taiwan, because
639273438Sdelphij# during the Qing Dynasty, it seems that there was no time zone
640273438Sdelphij# declared officially.
641273438Sdelphij#
642273438Sdelphij# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
643273438Sdelphij# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
644273438Sdelphij# revision in the ordinance No. 167 of Meiji year 28 about standard
645273438Sdelphij# time", in which abolished the adoption of Western Standard Time in
646273438Sdelphij# western islands (listed above), which means the whole Japan
647273438Sdelphij# territory, including later occupations, adopt Japan Central Time
648273438Sdelphij# (UTC+9). The adoption began on Oct 1, 1937. The original text can
649273438Sdelphij# be found on Wikisource:
650273438Sdelphij# http://ja.wikisource.org/wiki/���������������������������������������������������������������������������������
651273438Sdelphij#
652273438Sdelphij# That is, the time zone of Taipei switched to UTC+9 on Oct 1, 1937.
653206868Sedwin
654273438Sdelphij# From Yu-Cheng Chuang (2014-07-02):
655273438Sdelphij# I've found more evidence about when the time zone was switched from UTC+9
656273438Sdelphij# back to UTC+8 after WW2.  I believe it was on Sep 21, 1945.  In a document
657273438Sdelphij# during Japanese era [1] in which the officer told the staff to change time
658273438Sdelphij# zone back to Western Standard Time (UTC+8) on Sep 21.  And in another
659273438Sdelphij# history page of National Cheng Kung University [2], on Sep 21 there is a
660273438Sdelphij# note "from today, switch back to Western Standard Time".  From these two
661273438Sdelphij# materials, I believe that the time zone change happened on Sep 21.  And
662273438Sdelphij# today I have found another monthly journal called "The Astronomical Herald"
663273438Sdelphij# from The Astronomical Society of Japan [3] in which it mentioned the fact
664273438Sdelphij# that:
665273438Sdelphij#
666273438Sdelphij# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
667273438Sdelphij# the time at 135E (GMT+9)
668273438Sdelphij#
669273438Sdelphij# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
670273438Sdelphij# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
671273438Sdelphij# as well as Yaeyama and Miyako islands, adopted a new time zone called
672273438Sdelphij# Western Standard Time, which is in GMT+8.
673273438Sdelphij#
674273438Sdelphij# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
675273438Sdelphij# territories of Japan adopted the same time zone, which is Central Standard
676273438Sdelphij# Time.

686273438Sdelphij# I finally have found the real official gazette about changing back to
687273438Sdelphij# Western Standard Time on Sep 21 in Taiwan.  It's Taiwan Governor-General
688273438Sdelphij# Bulletin No. 386 in Showa 20 years (1945), published on Sep 19, 1945. [1] ...
689273438Sdelphij# [It] abolishes Bulletin No. 207 in Showa 12 years (1937), which is a local
690273438Sdelphij# bulletin in Taiwan for that Ordinance No. 529. It also mentioned that 1am on
691273438Sdelphij# Sep 21, 1945 will be 12am on Sep 21.  I think this bulletin is much more
692273438Sdelphij# official than the one I mentioned in my first mail, because it's from the
693273438Sdelphij# top-level government in Taiwan. If you're going to quote any resource, this
694273438Sdelphij# would be a good one.

1129149514Swollman# From Jonathan Lennox (2000-06-12):
113064499Swollman# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
113175267Swollman# the U.S. edition) on the Iraqi Kurds contains a paragraph:
113264499Swollman# "The three northern provinces ... switched their clocks this spring and
113364499Swollman# are an hour ahead of Baghdad."
113464499Swollman#
113564499Swollman# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
113664499Swollman# In the past, some Kurdish nationalists, as a protest to the Iraqi
113764499Swollman# Government, did not adhere to daylight saving time.  They referred
113864499Swollman# to daylight saving as Saddam time.  But, as of today, the time zone
113964499Swollman# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
114064499Swollman#
114164499Swollman# So we'll ignore the Economist's claim.

117575267Swollman# From Ephraim Silverberg (2001-01-11):
117675267Swollman#
117775267Swollman# I coined "IST/IDT" circa 1988.  Until then there were three
117875267Swollman# different abbreviations in use:
117975267Swollman#
118075267Swollman# JST  Jerusalem Standard Time [Danny Braniss, Hebrew University]
118175267Swollman# IZT  Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
118275267Swollman# EEST Eastern Europe Standard Time [used by almost everyone else]
118375267Swollman#
118475267Swollman# Since timezones should be called by country and not capital cities,
118575267Swollman# I ruled out JST.  As Israel is in Asia Minor and not Eastern Europe,
118675267Swollman# EEST was equally unacceptable.  Since "zonal" was not compatible with
118775267Swollman# any other timezone abbreviation, I felt that 'IST' was the way to go
118875267Swollman# and, indeed, it has received almost universal acceptance in timezone
118975267Swollman# settings in Israeli computers.
119075267Swollman#
119175267Swollman# In any case, I am happy to share timezone abbreviations with India,
119275267Swollman# high on my favorite-country list (and not only because my wife's
119375267Swollman# family is from India).

1243149514Swollman# From Ephraim Silverberg
1244149514Swollman# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
1245149514Swollman# and 2005-02-17):
124630711Swollman
12472742Swollman# According to the Office of the Secretary General of the Ministry of
12482742Swollman# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
124943543Swollman# One thing is entrenched in law, however: that there must be at least 150
125043543Swollman# days of daylight savings time annually.  From 1993-1998, the change to
125143543Swollman# daylight savings time was on a Friday morning from midnight IST to
125243543Swollman# 1 a.m IDT; up until 1998, the change back to standard time was on a
125343543Swollman# Saturday night from midnight daylight savings time to 11 p.m. standard
125443543Swollman# time.  1996 is an exception to this rule where the change back to standard
125543543Swollman# time took place on Sunday night instead of Saturday night to avoid
125664499Swollman# conflicts with the Jewish New Year.  In 1999, the change to
125764499Swollman# daylight savings time was still on a Friday morning but from
125843543Swollman# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
125964499Swollman# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
126064499Swollman# 1999 only.  In the year 2000, the change to daylight savings time was
126164499Swollman# similar to 1999, but although the change back will be on a Friday, it
126264499Swollman# will take place from 1 a.m. IDT to midnight IST.  Starting in 2001, all
126364499Swollman# changes to/from will take place at 1 a.m. old time, but now there is no
126464499Swollman# rule as to what day of the week it will take place in as the start date
126564499Swollman# (except in 2003) is the night after the Passover Seder (i.e. the eve
126664499Swollman# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
126764499Swollman# (except in 2002) is three nights before Yom Kippur [Day of Atonement]
126864499Swollman# (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1576273438Sdelphij# <http://www.kazsociety.org.uk/news/2005/03/30.htm> (2005-03-21):
1577149514Swollman# The Government of Kazakhstan passed a resolution March 15 abolishing
1578149514Swollman# daylight saving time citing lack of economic benefits and health
1579149514Swollman# complications coupled with a decrease in productivity.
158093799Swollman#
1581149514Swollman# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1582149514Swollman# ... what happened was that the former Kazakhstan Eastern time zone
1583149514Swollman# was "blended" with the Central zone.  Therefore, Kazakhstan now has
1584149514Swollman# two time zones, and difference between them is one hour.  The zone
1585149514Swollman# closer to UTC is the former Western zone (probably still called the
1586149514Swollman# same), encompassing four provinces in the west: Aqtobe, Atyrau,
1587149514Swollman# Mangghystau, and West Kazakhstan.  The other zone encompasses
1588149514Swollman# everything else....  I guess that would make Kazakhstan time zones
1589149514Swollman# de jure UTC+5 and UTC+6 respectively.

1613309568Sglebius# Estonian SSR; Komi ASSR; Kaliningrad oblast; Nenets autonomous okrug

1617309568Sglebius# of the Uzbek SSR were to move clocks 1 hour backwards.
1618309568Sglebius# Other territories were to not move clocks.
1619309568Sglebius# When the "summer" time would end on 1991-09-29, clocks were to be
1620309568Sglebius# moved 1 hour backwards on the territory of the USSR excluding
1621309568Sglebius# Kazakhstan, Kirghizia, Uzbekistan, Turkmenia, Tajikistan.
1622309568Sglebius#
1623309568Sglebius# Apparently there were last minute changes. Apparently Kazakh act No. 170

1628309568Sglebius# Nenets autonomous okrug, Komi and Kazakhstan (excluding Uralsk oblast)
1629309568Sglebius# were to not move clocks and Uralsk oblast was to move clocks
1630309568Sglebius# forward; on 1991-09-29 Kazakhstan was to move clocks backwards.
1631309568Sglebius# (Probably there were changes even after that publication. There is an

1634309568Sglebius#
1635309568Sglebius# This implies that on 1991-03-31 Asia/Oral remained on +04/+05 while

201558787Sru# From Rives McDow (1999-12-13):
201658787Sru# Mongolia discontinued the use of daylight savings time in 1999; 1998
201758787Sru# being the last year it was implemented.  The dates of implementation I am
201858787Sru# unsure of, but most probably it was similar to Russia, except for the time
201958787Sru# of implementation may have been different....
202058787Sru# Some maps in the past have indicated that there was an additional time
202158787Sru# zone in the eastern part of Mongolia, including the provinces of Dornod,

202658787Sru# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
202758787Sru# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
202858787Sru# and sometimes Jirgalanta (with variant spellings), but the name Hovd
202958787Sru# is good enough for our purposes.

23112742Swollman# Palestine
231243014Swollman
2313149514Swollman# From Amos Shapir (1998-02-15):
231443014Swollman#
231543014Swollman# From 1917 until 1948-05-15, all of Palestine, including the parts now
231643014Swollman# known as the Gaza Strip and the West Bank, was under British rule.
231743014Swollman# Therefore the rules given for Israel for that period, apply there too...
231843014Swollman#
231943014Swollman# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
232043014Swollman# (except a short occupation by Israel from 1956-11 till 1957-03, but no
232143014Swollman# time zone was affected then).  It was never formally annexed to Egypt,
232243014Swollman# though.
232343014Swollman#
232443014Swollman# The rest of Palestine was under Jordanian rule at that time, formally
232543014Swollman# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
232643014Swollman# the country's previous name of "the Hashemite Kingdom of the
232743014Swollman# Trans-Jordan").  So the rules for Jordan for that time apply.  Major
232843014Swollman# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
232943014Swollman# East Jerusalem.
233043014Swollman#
233143014Swollman# Both areas were occupied by Israel in June 1967, but not annexed (except
233243014Swollman# for East Jerusalem).  They were on Israel time since then; there might
233343014Swollman# have been a Military Governor's order about time zones, but I'm not aware
233443014Swollman# of any (such orders may have been issued semi-annually whenever summer
233543014Swollman# time was in effect, but maybe the legal aspect of time was just neglected).
233643014Swollman#
233743014Swollman# The Palestinian Authority was established in 1993, and got hold of most
233843014Swollman# towns in the West Bank and Gaza by 1995.  I know that in order to
233943014Swollman# demonstrate...independence, they have been switching to
234043014Swollman# summer time and back on a different schedule than Israel's, but I don't
234143014Swollman# know when this was started, or what algorithm is used (most likely the
234243014Swollman# Jordanian one).
234343014Swollman#
234443014Swollman# To summarize, the table should probably look something like that:
234543014Swollman#
234643014Swollman# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-

2355158421Swollman# From Paul Eggert (2006-03-22):
2356158421Swollman# Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
235743014Swollman# with Shapir and assume that it observed DST from 1940 through 1947,
235843014Swollman# and that it used Jordanian rules starting in 1996.
235943014Swollman# We don't yet need a separate entry for the West Bank, since
236043014Swollman# the only differences between it and Gaza that we know about
236143014Swollman# occurred before our cutoff date of 1970.
236243014Swollman# However, as we get more information, we may need to add entries
236343014Swollman# for parts of the West Bank as they transitioned from Israel's rules
2364243020Sedwin# to Palestine's rules.

2387158421Swollman# A user from Gaza reported that Gaza made the change early because of

2413172479Sedwin# From Paul Eggert (2007-09-20):
2414172479Sedwin# My understanding is that Gaza and the West Bank disagree even over when

2687273438Sdelphij# Time in Saudi Arabia and other countries in the Arabian peninsula was not
2688273438Sdelphij# standardized until relatively recently; we don't know when, and possibly it

2690273438Sdelphij# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
2691273438Sdelphij# observed standard time, and that people in Jeddah mostly observed quasi-solar
2692273438Sdelphij# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12

2694273438Sdelphij#
2695273438Sdelphij# The TZ database cannot represent quasi-solar time; airline time is the best
2696273438Sdelphij# we can do.  The 1946 foreign air news digest of the U.S. Civil Aeronautics
2697273438Sdelphij# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated

2701273438Sdelphij#
2702273438Sdelphij# Shanks & Pottenger also state that until 1968-05-01 Saudi Arabia had two

3023309568Sglebius#
3024309568Sglebius# The 1906 transition was effective July 1 and standardized Indochina to
3025309568Sglebius# Ph�� Li���n Observatory, legally 104 deg. 17'17" east of Paris.
3026309568Sglebius# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
3027309568Sglebius# the Paris Meridian (2 deg. 20'14.03" E); the former yields 07:06:30.1333...
3028309568Sglebius# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
3029309568Sglebius# which is used below even though the modern-day Ph�� Li���n Observatory
3030309568Sglebius# is closer to 07:06:31.  Abbreviate Ph�� Li���n Mean Time as PLMT.
