4 # go ahead and edit the file (and please send any changes to

7 # From Paul Eggert <eggert@twinsun.com> (1999-03-22):
8 #
9 # A good source for time zone historical data outside the U.S. is
10 # Thomas G. Shanks, The International Atlas (5th edition),
11 # San Diego: ACS Publications, Inc. (1999).
12 #
13 # Gwillim Law <Gwil_Law@bridge-point.com> writes that a good source
14 # for recent time zone data is the International Air Transport
15 # Association's Standard Schedules Information Manual (IATA SSIM),
16 # published semiannually. Law sent in several helpful summaries
17 # of the IATA's data after 1990.
18 #
19 # Except where otherwise noted, Shanks is the source for entries through 1990,
20 # and IATA SSIM is the source for entries after 1990.
21 #
22 # Another source occasionally used is Edward W. Whitman, World Time Differences,
23 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
24 # I found in the UCLA library.
25 #
26 # A reliable and entertaining source about time zones is
27 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

29 # I invented the abbreviations marked `*' in the following table;

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

167 # From Guy Harris:
168 # People's Republic of China. Yes, they really have only one time zone.
170 # From Bob Devine (1988-01-28):
171 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
172 # China is across 4 physical time zones, before Feb 1, 1986 only the
173 # Peking (Bejing) time zone was recognized. Since that date, China
174 # has two of 'em -- Peking's and Urumqi (named after the capital of
175 # the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
176 #
177 # . . .I just deleted the DST table and this editor makes it too

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

511 # An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
512 # the U.S. edition) on the Iraqi Kurds contains a paragraph:
513 # "The three northern provinces ... switched their clocks this spring and
514 # are an hour ahead of Baghdad."
515 #
516 # But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
517 # In the past, some Kurdish nationalists, as a protest to the Iraqi
518 # Government, did not adhere to daylight saving time. They referred
519 # to daylight saving as Saddam time. But, as of today, the time zone
520 # in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
521 #
522 # So we'll ignore the Economist's claim.

544 # Israel
546 # From Ephraim Silverberg (2001-01-11):
547 #
548 # I coined "IST/IDT" circa 1988. Until then there were three
549 # different abbreviations in use:
550 #
551 # JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
552 # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
553 # EEST Eastern Europe Standard Time [used by almost everyone else]
554 #
555 # Since timezones should be called by country and not capital cities,
556 # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
557 # EEST was equally unacceptable. Since "zonal" was not compatible with
558 # any other timezone abbreviation, I felt that 'IST' was the way to go
559 # and, indeed, it has received almost universal acceptance in timezone
560 # settings in Israeli computers.
561 #
562 # In any case, I am happy to share timezone abbreviations with India,
563 # high on my favorite-country list (and not only because my wife's
564 # family is from India).

612 # According to the Office of the Secretary General of the Ministry of
613 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
614 # One thing is entrenched in law, however: that there must be at least 150
615 # days of daylight savings time annually. From 1993-1998, the change to
616 # daylight savings time was on a Friday morning from midnight IST to
617 # 1 a.m IDT; up until 1998, the change back to standard time was on a
618 # Saturday night from midnight daylight savings time to 11 p.m. standard
619 # time. 1996 is an exception to this rule where the change back to standard
620 # time took place on Sunday night instead of Saturday night to avoid
621 # conflicts with the Jewish New Year. In 1999, the change to
622 # daylight savings time was still on a Friday morning but from
623 # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
624 # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
625 # 1999 only. In the year 2000, the change to daylight savings time was
626 # similar to 1999, but although the change back will be on a Friday, it
627 # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
628 # changes to/from will take place at 1 a.m. old time, but now there is no
629 # rule as to what day of the week it will take place in as the start date
630 # (except in 2003) is the night after the Passover Seder (i.e. the eve
631 # of the 16th of Nisan in the lunar Hebrew calendar) and the end date
632 # (except in 2002) is three nights before Yom Kippur [Day of Atonement]

748 # which stands for the time on E 135 degree.
749 # In the ordinance No. 167 (1895), "standard time" was renamed to "central
750 # standard time". And the same ordinance also established "western standard
751 # time", which stands for the time on E 120 degree.... But "western standard
752 # time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
753 # 167, there is no mention regarding for what place western standard time is
754 # standard....
755 #
756 # I wrote "ordinance" above, but I don't know how to translate.
757 # In Japanese it's "chokurei", which means ordinance from emperor.
759 # Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki)
760 # use +0800; go with Suzuki. Guess that all ordinances took effect on Jan 1.

983 # From Paul Eggert (1999-12-15):

1051 # Palestine
1053 # From Amos Shapir <amos@nsof.co.il> (1998-02-15):
1054 #
1055 # From 1917 until 1948-05-15, all of Palestine, including the parts now
1056 # known as the Gaza Strip and the West Bank, was under British rule.
1057 # Therefore the rules given for Israel for that period, apply there too...
1058 #
1059 # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1060 # (except a short occupation by Israel from 1956-11 till 1957-03, but no
1061 # time zone was affected then). It was never formally annexed to Egypt,
1062 # though.
1063 #
1064 # The rest of Palestine was under Jordanian rule at that time, formally
1065 # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1066 # the country's previous name of "the Hashemite Kingdom of the
1067 # Trans-Jordan"). So the rules for Jordan for that time apply. Major
1068 # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1069 # East Jerusalem.
1070 #
1071 # Both areas were occupied by Israel in June 1967, but not annexed (except
1072 # for East Jerusalem). They were on Israel time since then; there might
1073 # have been a Military Governor's order about time zones, but I'm not aware
1074 # of any (such orders may have been issued semi-annually whenever summer
1075 # time was in effect, but maybe the legal aspect of time was just neglected).
1076 #
1077 # The Palestinian Authority was established in 1993, and got hold of most
1078 # towns in the West Bank and Gaza by 1995. I know that in order to
1079 # demonstrate...independence, they have been switching to
1080 # summer time and back on a different schedule than Israel's, but I don't
1081 # know when this was started, or what algorithm is used (most likely the
1082 # Jordanian one).
1083 #
1084 # To summarize, the table should probably look something like that:
1085 #
1086 # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1087 # ------------+-----------+-----------+-----------+-----------
1088 # Israel | Zion | Zion | Zion | Zion
1089 # West bank | Zion | Jordan | Zion | Jordan
1090 # Gaza | Zion | Egypt | Zion | Jordan
1091 #
1092 # I guess more info may be available from the PA's web page (if/when they
1093 # have one).
1095 # From Paul Eggert (1998-02-25):
1096 # Shanks writes that Gaza did not observe DST until 1957, but we'll go
1097 # with Shapir and assume that it observed DST from 1940 through 1947,
1098 # and that it used Jordanian rules starting in 1996.
1099 # We don't yet need a separate entry for the West Bank, since
1100 # the only differences between it and Gaza that we know about
1101 # occurred before our cutoff date of 1970.
1102 # However, as we get more information, we may need to add entries
1103 # for parts of the West Bank as they transitioned from Israel's rules
1104 # to Palestine's rules. If you have more info about this, please
1105 # send it to tz@elsie.nci.nih.gov for incorporation into future editions.
1107 # From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
1108 # forwarded by Ephraim Silverberg:
1109 #
1110 # Despite the fact that Israel changed over to daylight savings time
1111 # last week, the PLO Authority (PA) has decided not to turn its clocks
1112 # one-hour forward at this time. As a sign of independence from Israeli rule,
1113 # the PA has decided to implement DST in April.
