# @(#)asia 7.5
# From Guy Harris:

# additional information from Tom Yap, Sun Microsystems Intercontinental
# Technical Support (including a page from the Official Airline Guide -
# Worldwide Edition). The names for time zones are guesses.

# 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 Ephraim Silverberg (April 18, 1989):
#
# Prior to 1989, the rules concerning Daylight Savings Time changed every
# year; as information, regarding exact times and dates during this period,
# is not readily available at the present time, the rules commence starting
# with the year 1989.
# From Ephraim Silverberg (September 5, 1993):
#
# 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 on daylight savings
# time annually.
