357 +# A Study on the Standard Time Changes for the Past 100 Years in China
358 +# [undated and unknown publication location]
359 +# It says several things:
360 +# * The Qing dynasty used local apparent solar time throughout China.
361 +# * The Republic of China instituted Beijing mean solar time effective
362 +# the official calendar book of 1914.
363 +# * The French Concession in Shanghai set up signal stations in
364 +# French docks in the 1890s, controlled by Xujiahui (Zikawei)
365 +# Observatory and set to local mean time.
366 +# * "From the end of the 19th century" it changed to UT+8.
367 +# * Chinese Customs (by then reduced to a tool of foreign powers)
368 +# eventually standardized on this time for all ports, and it
369 +# became used by railways as well.
370 +# * In 1918 the Central Observatory proposed dividing China into
371 +# five time zones (see below for details). This caught on
372 +# at first only in coastal areas observing UT+8.
373 +# * During WWII all of China was in theory was at UT+7. In practice
374 +# this was ignored in the west, and I presume was ignored in
375 +# Japanese-occupied territory.
376 +# * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.
377 +# * The five-zone plan was resurrected after WWII and officially put into
378 +# place (with some modifications) in March 1948. It's not clear
379 +# how well it was observed in areas under Nationalist control.
380 +# * The People's Liberation Army used UT+8 during the civil war.

634 +# On Dec 28, 1895, the Meiji Emperor announced Ordinance No. 167 of
635 +# Meiji Year 28 "The clause about standard time", mentioned that
636 +# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
637 +# (both in Okinawa) adopt the Western Standard Time which is based on
638 +# 120E. The adoption began from Jan 1, 1896. The original text can be
639 +# found on Wikisource:
640 +# http://ja.wikisource.org/wiki/標準時ニ關スル件_(公布時)
641 +# ... This could be the first adoption of time zone in Taiwan, because
642 +# during the Qing Dynasty, it seems that there was no time zone
643 +# declared officially.
644 +#
645 +# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
646 +# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
647 +# revision in the ordinance No. 167 of Meiji year 28 about standard
648 +# time", in which abolished the adoption of Western Standard Time in
649 +# western islands (listed above), which means the whole Japan
650 +# territory, including later occupations, adopt Japan Central Time
651 +# (UTC+9). The adoption began on Oct 1, 1937. The original text can
652 +# be found on Wikisource:
653 +# http://ja.wikisource.org/wiki/明治二十八年勅令第百六十七號標準時ニ關スル件中改正ノ件
654 +#
655 +# That is, the time zone of Taipei switched to UTC+9 on Oct 1, 1937.
617 656
657 +# From Yu-Cheng Chuang (2014-07-02):
658 +# I've found more evidence about when the time zone was switched from UTC+9
659 +# back to UTC+8 after WW2. I believe it was on Sep 21, 1945. In a document
660 +# during Japanese era [1] in which the officer told the staff to change time
661 +# zone back to Western Standard Time (UTC+8) on Sep 21. And in another
662 +# history page of National Cheng Kung University [2], on Sep 21 there is a
663 +# note "from today, switch back to Western Standard Time". From these two
664 +# materials, I believe that the time zone change happened on Sep 21. And
665 +# today I have found another monthly journal called "The Astronomical Herald"
666 +# from The Astronomical Society of Japan [3] in which it mentioned the fact
667 +# that:
668 +#
669 +# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
670 +# the time at 135E (GMT+9)
671 +#
672 +# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
673 +# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
674 +# as well as Yaeyama and Miyako islands, adopted a new time zone called
675 +# Western Standard Time, which is in GMT+8.
676 +#
677 +# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
678 +# territories of Japan adopted the same time zone, which is Central Standard
679 +# Time.

691 +# Bulletin No. 386 in Showa 20 years (1945), published on Sep 19, 1945. [1] ...
692 +# [It] abolishes Bulletin No. 207 in Showa 12 years (1937), which is a local
693 +# bulletin in Taiwan for that Ordinance No. 529. It also mentioned that 1am on
694 +# Sep 21, 1945 will be 12am on Sep 21. I think this bulletin is much more
695 +# official than the one I mentioned in my first mail, because it's from the

697 +# would be a good one.

1033 1146 # From Ephraim Silverberg (2001-01-11):
1034 1147 #
1035 1148 # I coined "IST/IDT" circa 1988. Until then there were three
1036 1149 # different abbreviations in use:
1037 1150 #
1038 1151 # JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
1039 1152 # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
1040 1153 # EEST Eastern Europe Standard Time [used by almost everyone else]
1041 1154 #
1042 1155 # Since timezones should be called by country and not capital cities,
1043 1156 # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
1044 1157 # EEST was equally unacceptable. Since "zonal" was not compatible with
1045 1158 # any other timezone abbreviation, I felt that 'IST' was the way to go
1046 1159 # and, indeed, it has received almost universal acceptance in timezone
1047 1160 # settings in Israeli computers.
1048 1161 #
1049 1162 # In any case, I am happy to share timezone abbreviations with India,
1050 1163 # high on my favorite-country list (and not only because my wife's
1051 1164 # family is from India).

1098 1216 # and 2005-02-17):
1099 1217
1100 1218 # According to the Office of the Secretary General of the Ministry of
1101 1219 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
1102 1220 # One thing is entrenched in law, however: that there must be at least 150
1103 1221 # days of daylight savings time annually. From 1993-1998, the change to
1104 1222 # daylight savings time was on a Friday morning from midnight IST to
1105 1223 # 1 a.m IDT; up until 1998, the change back to standard time was on a
1106 1224 # Saturday night from midnight daylight savings time to 11 p.m. standard
1107 1225 # time. 1996 is an exception to this rule where the change back to standard
1108 1226 # time took place on Sunday night instead of Saturday night to avoid
1109 1227 # conflicts with the Jewish New Year. In 1999, the change to
1110 1228 # daylight savings time was still on a Friday morning but from
1111 1229 # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
1112 1230 # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
1113 1231 # 1999 only. In the year 2000, the change to daylight savings time was
1114 1232 # similar to 1999, but although the change back will be on a Friday, it
1115 1233 # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
1116 1234 # changes to/from will take place at 1 a.m. old time, but now there is no
1117 1235 # rule as to what day of the week it will take place in as the start date
1118 1236 # (except in 2003) is the night after the Passover Seder (i.e. the eve
1119 1237 # of the 16th of Nisan in the lunar Hebrew calendar) and the end date
1120 1238 # (except in 2002) is three nights before Yom Kippur [Day of Atonement]

2036 2096 # From 1917 until 1948-05-15, all of Palestine, including the parts now
2037 2097 # known as the Gaza Strip and the West Bank, was under British rule.
2038 2098 # Therefore the rules given for Israel for that period, apply there too...
2039 2099 #
2040 2100 # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
2041 2101 # (except a short occupation by Israel from 1956-11 till 1957-03, but no
2042 2102 # time zone was affected then). It was never formally annexed to Egypt,
2043 2103 # though.
2044 2104 #
2045 2105 # The rest of Palestine was under Jordanian rule at that time, formally
2046 2106 # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
2047 2107 # the country's previous name of "the Hashemite Kingdom of the
2048 2108 # Trans-Jordan"). So the rules for Jordan for that time apply. Major
2049 2109 # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
2050 2110 # East Jerusalem.
2051 2111 #
2052 2112 # Both areas were occupied by Israel in June 1967, but not annexed (except
2053 2113 # for East Jerusalem). They were on Israel time since then; there might
2054 2114 # have been a Military Governor's order about time zones, but I'm not aware
2055 2115 # of any (such orders may have been issued semi-annually whenever summer
2056 2116 # time was in effect, but maybe the legal aspect of time was just neglected).
2057 2117 #
2058 2118 # The Palestinian Authority was established in 1993, and got hold of most
2059 2119 # towns in the West Bank and Gaza by 1995. I know that in order to
2060 2120 # demonstrate...independence, they have been switching to
2061 2121 # summer time and back on a different schedule than Israel's, but I don't
2062 2122 # know when this was started, or what algorithm is used (most likely the
2063 2123 # Jordanian one).

2437 +# From Paul Eggert (2014-07-15):
2438 +# Time in Saudi Arabia and other countries in the Arabian peninsula was not
2439 +# standardized until relatively recently; we don't know when, and possibly it
2440 +# has never been made official. Richard P Hunt, in "Islam city yielding to
2441 +# modern times", New York Times (1961-04-09), p 20, wrote that only airlines
2442 +# observed standard time, and that people in Jeddah mostly observed quasi-solar
2443 +# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
2444 +# o'clock for "Arab" time).
2445 +#
2446 +# The TZ database cannot represent quasi-solar time; airline time is the best
2447 +# we can do. The 1946 foreign air news digest of the U.S. Civil Aeronautics
2448 +# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated
2449 +# a weekly Dhahran-Cairo service, via the Saudi Arabian cities of Riyadh and
2450 +# Jidda, on March 14, 1947". Shanks & Pottenger guessed 1950; go with the
2451 +# earlier date.
2452 +#
2453 +# Shanks & Pottenger also state that until 1968-05-01 Saudi Arabia had two
2454 +# time zones; the other zone, at UTC+4, was in the far eastern part of
2455 +# the country. Ignore this, as it's before our 1970 cutoff.
