# 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;

# Armenia
|
|
# 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. 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 - ??
|
|

# 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.

# an MP who went on a hunger strike for 11 days to force discussion about it!
|

# We have no details, but we'll guess they didn't move the clocks back in fall.

# From Paul Eggert (1995-11-13):

# usno1995 has Georgia at 4:00. Guess that Georgia stopped transitions

# 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.
