6 # go ahead and edit the file (and please send any changes to
7 # tz@elsie.nci.nih.gov for general use in the future).
9 # From Paul Eggert <eggert@twinsun.com> (1999-03-22):
11 # A good source for time zone historical data outside the U.S. is
12 # Thomas G. Shanks, The International Atlas (5th edition),
13 # San Diego: ACS Publications, Inc. (1999).
15 # Gwillim Law <Gwil_Law@bridge-point.com> writes that a good source
16 # for recent time zone data is the International Air Transport
17 # Association's Standard Schedules Information Manual (IATA SSIM),
18 # published semiannually. Law sent in several helpful summaries
19 # of the IATA's data after 1990.
21 # Except where otherwise noted, Shanks is the source for entries through 1990,
22 # and IATA SSIM is the source for entries after 1990.
24 # Another source occasionally used is Edward W. Whitman, World Time Differences,
25 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
26 # I found in the UCLA library.
28 # A reliable and entertaining source about time zones is
29 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
31 # I invented the abbreviations marked `*' in the following table;
32 # the rest are from earlier versions of this file, or from other sources.

82 # From Paul Eggert (1999-10-29):
83 # Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991,
84 # then to 4:00 with no DST in fall 1995, then readopting Russian DST in 1997.
85 # Go with Shanks, even when he disagrees with others. Edgar Der-Danieliantz
86 # <edd@AIC.NET> reported (1996-05-04) that Yerevan probably wouldn't use DST
87 # in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that
88 # Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,
89 # but started switching at 3:00s in 1998.

167 # From Bob Devine (1988-01-28):
168 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
169 # China is across 4 physical time zones, before Feb 1, 1986 only the

185 # From Paul Eggert <eggert@twinsun.com> (1995-12-19):
186 # Shanks writes that China has had a single time zone since 1980 May 1,
187 # observing summer DST from 1986 through 1991; this contradicts Devine's
188 # note about Time magazine, though apparently _something_ happened in 1986.

492 # An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in

494 # "The three northern provinces ... switched their clocks this spring and
495 # are an hour ahead of Baghdad."
497 # But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
498 # In the past, some Kurdish nationalists, as a protest to the Iraqi
499 # Government, did not adhere to daylight saving time. They referred
500 # to daylight saving as Saddam time. But, as of today, the time zone
501 # in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
503 # So we'll ignore the Economist's claim.

527 # From Ephraim Silverberg (2001-01-11):
529 # I coined "IST/IDT" circa 1988. Until then there were three
530 # different abbreviations in use:
532 # JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
533 # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
534 # EEST Eastern Europe Standard Time [used by almost everyone else]
536 # Since timezones should be called by country and not capital cities,
537 # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
538 # EEST was equally unacceptable. Since "zonal" was not compatible with
539 # any other timezone abbreviation, I felt that 'IST' was the way to go
540 # and, indeed, it has received almost universal acceptance in timezone
541 # settings in Israeli computers.
543 # In any case, I am happy to share timezone abbreviations with India,
544 # high on my favorite-country list (and not only because my wife's
545 # family is from India).

593 # According to the Office of the Secretary General of the Ministry of
594 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
595 # One thing is entrenched in law, however: that there must be at least 150
596 # days of daylight savings time annually. From 1993-1998, the change to
597 # daylight savings time was on a Friday morning from midnight IST to
598 # 1 a.m IDT; up until 1998, the change back to standard time was on a
599 # Saturday night from midnight daylight savings time to 11 p.m. standard
600 # time. 1996 is an exception to this rule where the change back to standard
601 # time took place on Sunday night instead of Saturday night to avoid
602 # conflicts with the Jewish New Year. In 1999, the change to
603 # daylight savings time was still on a Friday morning but from
604 # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
605 # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
606 # 1999 only. In the year 2000, the change to daylight savings time was
607 # similar to 1999, but although the change back will be on a Friday, it
608 # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
609 # changes to/from will take place at 1 a.m. old time, but now there is no
610 # rule as to what day of the week it will take place in as the start date
611 # (except in 2003) is the night after the Passover Seder (i.e. the eve
612 # of the 16th of Nisan in the lunar Hebrew calendar) and the end date

724 # JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
725 # The law is enacted on 1886-07-07.
727 # From Hideyuki Suzuki (1998-11-16):
728 # The ordinance No. 51 (1886) established "standard time" in Japan,
729 # which stands for the time on E 135 degree.
730 # In the ordinance No. 167 (1895), "standard time" was renamed to "central
731 # standard time". And the same ordinance also established "western standard
732 # time", which stands for the time on E 120 degree.... But "western standard
733 # time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
734 # 167, there is no mention regarding for what place western standard time is
737 # I wrote "ordinance" above, but I don't know how to translate.
738 # In Japanese it's "chokurei", which means ordinance from emperor.
740 # Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki)

1020 # From Amos Shapir <amos@nsof.co.il> (1998-02-15):
1022 # From 1917 until 1948-05-15, all of Palestine, including the parts now
1023 # known as the Gaza Strip and the West Bank, was under British rule.
1024 # Therefore the rules given for Israel for that period, apply there too...
1026 # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1027 # (except a short occupation by Israel from 1956-11 till 1957-03, but no
1028 # time zone was affected then). It was never formally annexed to Egypt,
1031 # The rest of Palestine was under Jordanian rule at that time, formally
1032 # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1033 # the country's previous name of "the Hashemite Kingdom of the
1034 # Trans-Jordan"). So the rules for Jordan for that time apply. Major
1035 # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1038 # Both areas were occupied by Israel in June 1967, but not annexed (except
1039 # for East Jerusalem). They were on Israel time since then; there might
1040 # have been a Military Governor's order about time zones, but I'm not aware
1041 # of any (such orders may have been issued semi-annually whenever summer
1042 # time was in effect, but maybe the legal aspect of time was just neglected).
1044 # The Palestinian Authority was established in 1993, and got hold of most
1045 # towns in the West Bank and Gaza by 1995. I know that in order to
1046 # demonstrate...independence, they have been switching to
1047 # summer time and back on a different schedule than Israel's, but I don't

1062 # From Paul Eggert (1998-02-25):
1063 # Shanks writes that Gaza did not observe DST until 1957, but we'll go
1064 # with Shapir and assume that it observed DST from 1940 through 1947,
1065 # and that it used Jordanian rules starting in 1996.
1066 # We don't yet need a separate entry for the West Bank, since
1067 # the only differences between it and Gaza that we know about
1068 # occurred before our cutoff date of 1970.
1069 # However, as we get more information, we may need to add entries
1070 # for parts of the West Bank as they transitioned from Israel's rules
1071 # to Palestine's rules. If you have more info about this, please

1077 # Despite the fact that Israel changed over to daylight savings time
1078 # last week, the PLO Authority (PA) has decided not to turn its clocks
