-
- # From Paul Eggert <eggert@twinsun.com> (1995-12-19):
- #
- # A good source for time zone historical data outside the U.S. is
- # Thomas G. Shanks, The International Atlas (3rd edition),
- # San Diego: ACS Publications, Inc. (1991).
- # Except where otherwise noted, it is the source for the data below.
- #
- # Another source occasionally used is Edward W. Whitman, World Time Differences,
- # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
- # I found in the UCLA library.
- #
- # A reliable and entertaining source about time zones is
- # Derek Howse, Greenwich time and the discovery of the longitude,
- # Oxford University Press (1980).
- #
- # I invented the abbreviations marked `*' in the following table;
- # the rest are from earlier versions of this file, or from other sources.

- # From Paul Eggert (1996-05-04):
- # Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991,
- # but usno1995 has Armenia at 4:00 (with DST), and Edgar Der-Danieliantz
- # <edd@AIC.NET> reported today that Yerevan probably won't use DST this year,
- # though it did use DST in 1995. We guess Yerevan stayed in sync with Moscow
- # between 1990 and 1995, but stopped using DST in 1996.
- # Der-Danieliantz also asked for a better abbreviation than `YSK'
- # after independence. Apparently no abbreviation is in common use;
- # use `AMST/AMDT' since `AM' is the ISO country code for Armenia.

- # People's Republic of China
-
- # From Guy Harris:
- # People's Republic of China. Yes, they really have only one time zone.
-
- # From Bob Devine (January 28, 1988):
- # No they don't. See TIME mag, February 17, 1986 p.52. Even though
- # China is across 4 physical time zones, before Feb 1, 1986 only the
- # Peking (Bejing) time zone was recognized. Since that date, China
- # has two of 'em -- Peking's and Urumqi (named after the capital of
- # the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
- #
- # . . .I just deleted the DST table and this editor makes it too
- # painful to suck in another copy.. So, here is what I have for
- # DST start/end dates for Peking's time zone (info from AP):
- #
- # 1986 May 4 - Sept 14
- # 1987 mid-April - ??
-
- # From U. S. Naval Observatory (January 19, 1989):
- # CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
- # CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
-
- # From Paul Eggert <eggert@twinsun.com> (1995-12-19):
- # Shanks writes that China switched from the Chinese calendar on 1912 Feb 12.
- # He also writes that China has had a single time zone since 1980 May 1,
- # observing summer DST from 1986 through 1991; this contradicts Devine's
- # note about Time magazine, though apparently _something_ happened in 1986.
- # Go with Shanks for now. I made up names for the other pre-1980 time zones.

- # From Ephraim Silverberg (1996-01-02):
- #
- # According to the Office of the Secretary General of the Ministry of
- # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
- # Each year they decide anew what havoc to wreak on the country. However,
- # there is a "supposed" set of rules which is subject to change depending
- # on the party the Minister of Interior, the size of the coalition
- # government, the phase of the moon and the direction of the wind. Hence,
- # changes may need to be made on a semi-annual basis. One thing is entrenched
- # in law, however: that there must be at least 150 days of daylight savings
- # time annually. Ever since 1993, the change to daylight savings time has
- # been from midnight Thursday night to 1 a.m. Friday morning and the change
- # back to standard time on Saturday night from midnight daylight savings time
- # to 11 p.m. standard time. 1996 is an exception to this rule where the
- # change back to standard time takes place on Sunday night instead of Saturday
- # night to avoid conflicts with the Jewish New Year.
