# It says several things:
|
|
376 |
# * The Qing dynasty used local apparent solar time throughout China.
|
|
377 |
# * The Republic of China instituted Beijing mean solar time effective
|
|
378 |
# the official calendar book of 1914.
|
|
379 |
# * The French Concession in Shanghai set up signal stations in
|
|
380 |
# French docks in the 1890s, controlled by Xujiahui (Zikawei)
|
|
381 |
# Observatory and set to local mean time.
|
|
382 |
# * "From the end of the 19th century" it changed to UT+8.
|
|
383 |
# * Chinese Customs (by then reduced to a tool of foreign powers)
|
|
384 |
# eventually standardized on this time for all ports, and it
|
|
385 |
# became used by railways as well.
|
|
386 |
# * In 1918 the Central Observatory proposed dividing China into
|
|
387 |
# five time zones (see below for details). This caught on
|
|
388 |
# at first only in coastal areas observing UT+8.
|
|
389 |
# * During WWII all of China was in theory was at UT+7. In practice
|
|
390 |
# this was ignored in the west, and I presume was ignored in
|
|
391 |
# Japanese-occupied territory.
|
|
392 |
# * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
|
|
393 |
# * The five-zone plan was resurrected after WWII and officially put into
|
|
394 |
# place (with some modifications) in March 1948. It's not clear
|
|
395 |
# how well it was observed in areas under Nationalist control.

# An AP article "Shanghai Internat'l Area Little Changed" in the

|
|
400 |

# From Luther Ma (2009-10-17):
|
|
451 |
# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in
|
|
452 |
# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time,
|
|
453 |
# but have no need of it. All planes, trains, and schools function on
|
|
454 |
# what is called "Beijing time." When Han make an appointment in Chinese
|
|
455 |
# they implicitly use Beijing time.
|
|
456 |
#
|
|
457 |
# On the other hand, ethnic Uyghurs, who make up about half the
|
|
458 |
# population of Xinjiang, typically use "Xinjiang time" which is two
|
|
459 |
# hours behind Beijing time, or UTC +0600. The government of the Xinjiang
|
|
460 |
# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as
|
26452
|
461 |
# local governments such as the Ürümqi city government use both times in
|
4959
|
462 |
# publications, referring to what is popularly called Xinjiang time as
|
26452
|
463 |
# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language
|
4959
|
464 |
# they almost invariably use Xinjiang time.
|
|
465 |
#
|
|
466 |
# (Their ethnic Han compatriots would typically have no clue of its
|
|
467 |
# widespread use, however, because so extremely few of them are fluent in
|
|
468 |
# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.)
|
|
469 |
#
|
|
470 |
# (...As with the rest of China there was a brief interval ending in 1990
|
|
471 |
# or 1991 when summer time was in use. The confusion was severe, with

472 |
# the province not having dual times but four times in use at the same

474 |
# others moving their clocks ahead.)

# 5. It seems that Uyghurs in Ürümqi has been using Xinjiang since at least the
|
4959
|
486 |
# 1960's. I know of one Han, now over 50, who grew up in the surrounding

# report regarding Xinjiang, as well as the Time article reference by David
|
|
505 |
# Cochrane. Whether officially recognized or not (and both are officially

507 |
# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time;

|
508 |
# and Beijing Time. There is no confusion in Xinjiang as to which name refers

509 |
# to which time. Both are widely used in the province, although in some
|
|
510 |

# I found there are some mistakes for the...DST rule for Hong

554 |
# Kong. [According] to the DST record from Hong Kong Observatory (actually,

4279
|
555 |
# it is not [an] observatory, but the official meteorological agency of HK,
|
|
556 |
# and also serves as the official timing agency), there are some missing

557 |
# and incorrect rules. Although the exact switch over time is missing, I

648 |

|

# From Yu-Cheng Chuang (2013-07-12):
|
|
650 |
# On Dec 28, 1895, the Meiji Emperor announced Ordinance No. 167 of
|
|
651 |
# Meiji Year 28 "The clause about standard time", mentioned that
|
|
652 |
# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
|
|
653 |
# (both in Okinawa) adopt the Western Standard Time which is based on
|
|
654 |
# 120E. The adoption began from Jan 1, 1896. The original text can be
|
|
655 |
# found on Wikisource:
|
|
656 |
# http://ja.wikisource.org/wiki/標準時ニ關スル件_(公布時)
|
|
657 |
# ... This could be the first adoption of time zone in Taiwan, because
|
|
658 |
# during the Qing Dynasty, it seems that there was no time zone
|
|
659 |
# declared officially.
|
|
660 |
#
|
|
661 |
# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
|
|
662 |
# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
|
|
663 |
# revision in the ordinance No. 167 of Meiji year 28 about standard
|
|
664 |
# time", in which abolished the adoption of Western Standard Time in
|
|
665 |
# western islands (listed above), which means the whole Japan
|
|
666 |
# territory, including later occupations, adopt Japan Central Time
|
|
667 |
# (UTC+9). The adoption began on Oct 1, 1937. The original text can
|
|
668 |
# be found on Wikisource:

671 |
# That is, the time zone of Taipei switched to UTC+9 on Oct 1, 1937.
|
|
672 |
|
|
673 |
# From Yu-Cheng Chuang (2014-07-02):
|
|
674 |
# I've found more evidence about when the time zone was switched from UTC+9
|
|
675 |
# back to UTC+8 after WW2. I believe it was on Sep 21, 1945. In a document
|
|
676 |
# during Japanese era [1] in which the officer told the staff to change time
|
|
677 |
# zone back to Western Standard Time (UTC+8) on Sep 21. And in another
|
|
678 |
# history page of National Cheng Kung University [2], on Sep 21 there is a
|
|
679 |
# note "from today, switch back to Western Standard Time". From these two
|
|
680 |
# materials, I believe that the time zone change happened on Sep 21. And
|
|
681 |
# today I have found another monthly journal called "The Astronomical Herald"
|
|
682 |
# from The Astronomical Society of Japan [3] in which it mentioned the fact
|
|
683 |
# that:
|
|
684 |
#
|
|
685 |
# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
|
|
686 |
# the time at 135E (GMT+9)
|
|
687 |
#
|
|
688 |
# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
|
|
689 |
# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
|
|
690 |
# as well as Yaeyama and Miyako islands, adopted a new time zone called
|
|
691 |
# Western Standard Time, which is in GMT+8.
|
|
692 |
#
|
|
693 |
# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
|
|
694 |
# territories of Japan adopted the same time zone, which is Central Standard
|
|
695 |
# Time.

# From Jonathan Lennox (2000-06-12):
|
|
1121 |
# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
|
|
1122 |
# the U.S. edition) on the Iraqi Kurds contains a paragraph:
|
|
1123 |
# "The three northern provinces ... switched their clocks this spring and
|
|
1124 |
# are an hour ahead of Baghdad."
|
|
1125 |
#
|
|
1126 |
# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
|
|
1127 |
# In the past, some Kurdish nationalists, as a protest to the Iraqi
|
|
1128 |
# Government, did not adhere to daylight saving time. They referred
|
|
1129 |
# to daylight saving as Saddam time. But, as of today, the time zone
|
|
1130 |
# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
|
|
1131 |
#
|
|
1132 |
# So we'll ignore the Economist's claim.

# From Ephraim Silverberg (2001-01-11):
|
|
1167 |
#
|
|
1168 |
# I coined "IST/IDT" circa 1988. Until then there were three
|
|
1169 |
# different abbreviations in use:
|
|
1170 |
#
|
|
1171 |
# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
|
|
1172 |
# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
|
|
1173 |
# EEST Eastern Europe Standard Time [used by almost everyone else]
|
|
1174 |
#
|
|
1175 |
# Since timezones should be called by country and not capital cities,
|
|
1176 |
# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
|
|
1177 |
# EEST was equally unacceptable. Since "zonal" was not compatible with
|
|
1178 |
# any other timezone abbreviation, I felt that 'IST' was the way to go
|
|
1179 |
# and, indeed, it has received almost universal acceptance in timezone
|
|
1180 |
# settings in Israeli computers.
|
|
1181 |
#
|
|
1182 |
# In any case, I am happy to share timezone abbreviations with India,
|
|
1183 |
# high on my favorite-country list (and not only because my wife's
|
|
1184 |
# family is from India).

|
|
1236 |
# and 2005-02-17):
|
|
1237 |
|
|
1238 |
# According to the Office of the Secretary General of the Ministry of
|
|
1239 |
# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
|
|
1240 |
# One thing is entrenched in law, however: that there must be at least 150
|
|
1241 |
# days of daylight savings time annually. From 1993-1998, the change to
|
|
1242 |
# daylight savings time was on a Friday morning from midnight IST to
|
|
1243 |
# 1 a.m IDT; up until 1998, the change back to standard time was on a
|
|
1244 |
# Saturday night from midnight daylight savings time to 11 p.m. standard
|
|
1245 |
# time. 1996 is an exception to this rule where the change back to standard
|
|
1246 |
# time took place on Sunday night instead of Saturday night to avoid
|
|
1247 |
# conflicts with the Jewish New Year. In 1999, the change to
|
|
1248 |
# daylight savings time was still on a Friday morning but from
|
|
1249 |
# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
|
|
1250 |
# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
|
|
1251 |
# 1999 only. In the year 2000, the change to daylight savings time was
|
|
1252 |
# similar to 1999, but although the change back will be on a Friday, it
|
|
1253 |
# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
|
|
1254 |
# changes to/from will take place at 1 a.m. old time, but now there is no
|
|
1255 |
# rule as to what day of the week it will take place in as the start date
|
|
1256 |
# (except in 2003) is the night after the Passover Seder (i.e. the eve
|
|
1257 |
# of the 16th of Nisan in the lunar Hebrew calendar) and the end date
|
|
1258 |
# (except in 2002) is three nights before Yom Kippur [Day of Atonement]

# From Paul Eggert (1996-11-22):
|
|
1567 |
# Andrew Evtichov (1996-04-13) writes that Kazakhstan
|
|
1568 |
# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
|
|
1569 |
# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
|
|
1570 |
# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
|
|
1571 |
# IATA SSIM mentions a third time zone in Kazakhstan.
|
|
1572 |
|
|
1573 |
# From Paul Eggert (2006-03-22):
|
|
1574 |
# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
|
|
1575 |
# RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
|
|
1576 |
# Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
|
|
1577 |
# Also go with the following claims of Shanks & Pottenger:
|
|
1578 |
#
|
|
1579 |
# - Kazakhstan did not observe DST in 1991.
|
|
1580 |
# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.
|

1581 |
# - Oral switched from +5:00 to +4:00 in spring 1989.

# The Government of Kazakhstan passed a resolution March 15 abolishing
|
|
1586 |
# daylight saving time citing lack of economic benefits and health
|
|
1587 |
# complications coupled with a decrease in productivity.

#
|
|
1589 |
# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
|
|
1590 |
# ... what happened was that the former Kazakhstan Eastern time zone
|
|
1591 |
# was "blended" with the Central zone. Therefore, Kazakhstan now has
|
|
1592 |
# two time zones, and difference between them is one hour. The zone
|
|
1593 |
# closer to UTC is the former Western zone (probably still called the
|
|
1594 |
# same), encompassing four provinces in the west: Aqtobe, Atyrau,
|
|
1595 |
# Mangghystau, and West Kazakhstan. The other zone encompasses
|
|
1596 |
# everything else.... I guess that would make Kazakhstan time zones

# Palestine
|
|
2137 |
|
|
2138 |
# From Amos Shapir (1998-02-15):
|
|
2139 |
#
|
|
2140 |
# From 1917 until 1948-05-15, all of Palestine, including the parts now
|
|
2141 |
# known as the Gaza Strip and the West Bank, was under British rule.
|
|
2142 |
# Therefore the rules given for Israel for that period, apply there too...
|
|
2143 |
#
|
|
2144 |
# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
|
|
2145 |
# (except a short occupation by Israel from 1956-11 till 1957-03, but no
|
|
2146 |
# time zone was affected then). It was never formally annexed to Egypt,
|
|
2147 |
# though.
|
|
2148 |
#
|
|
2149 |
# The rest of Palestine was under Jordanian rule at that time, formally
|
|
2150 |
# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
|
|
2151 |
# the country's previous name of "the Hashemite Kingdom of the
|
|
2152 |
# Trans-Jordan"). So the rules for Jordan for that time apply. Major
|
|
2153 |
# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
|
|
2154 |
# East Jerusalem.
|
|
2155 |
#
|
|
2156 |
# Both areas were occupied by Israel in June 1967, but not annexed (except
|
|
2157 |
# for East Jerusalem). They were on Israel time since then; there might
|
|
2158 |
# have been a Military Governor's order about time zones, but I'm not aware
|
|
2159 |
# of any (such orders may have been issued semi-annually whenever summer
|
|
2160 |
# time was in effect, but maybe the legal aspect of time was just neglected).
|
|
2161 |
#
|
|
2162 |
# The Palestinian Authority was established in 1993, and got hold of most
|
|
2163 |
# towns in the West Bank and Gaza by 1995. I know that in order to
|
|
2164 |
# demonstrate...independence, they have been switching to
|
|
2165 |
# summer time and back on a different schedule than Israel's, but I don't
|
|
2166 |
# know when this was started, or what algorithm is used (most likely the
|
|
2167 |
# Jordanian one).

|
2183 |
# and that it used Jordanian rules starting in 1996.
|

2184 |
# We don't yet need a separate entry for the West Bank, since

2185 |
# the only differences between it and Gaza that we know about

2186 |

|

2491 |
# Time in Saudi Arabia and other countries in the Arabian peninsula was not
|
|
2492 |
# standardized until relatively recently; we don't know when, and possibly it
|
|
2493 |
# has never been made official. Richard P Hunt, in "Islam city yielding to
|
|
2494 |
# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
|
|
2495 |
# observed standard time, and that people in Jeddah mostly observed quasi-solar
|
|
2496 |
# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
|
|
2497 |
# o'clock for "Arab" time).
|
|
2498 |
#
|
|
2499 |
# The TZ database cannot represent quasi-solar time; airline time is the best
|
|
2500 |
# we can do. The 1946 foreign air news digest of the U.S. Civil Aeronautics
|
|
2501 |
# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated
|
|
2502 |
# a weekly Dhahran-Cairo service, via the Saudi Arabian cities of Riyadh and
|
|
2503 |
# Jidda, on March 14, 1947". Shanks & Pottenger guessed 1950; go with the

# earlier date.

# and is the basis for the information below.

#

# The 1906 transition was effective July 1 and standardized Indochina to
|
|
2846 |
# Phù Liễn Observatory, legally 104 deg. 17'17" east of Paris.
|
|
2847 |
# It's unclear whether this meant legal Paris Mean Time (00:09:21) or
|
|
2848 |
# the Paris Meridian (2 deg. 20'14.03" E); the former yields 07:06:30.1333...
|
|
2849 |
# and the latter 07:06:29.333... so either way it rounds to 07:06:30,
|
|
2850 |
# which is used below even though the modern-day Phù Liễn Observatory
|
|
2851 |
# is closer to 07:06:31. Abbreviate Phù Liễn Mean Time as PLMT.
|
|
2852 |

|

2853 |
# The following transitions occurred in Indochina in general (before 1954)
|
|
2854 |
# and in South Vietnam in particular (after 1954):
|
|
2855 |
# To 07:00 on 1911-05-01.
