The government of the Xinjiang 412200835Sedwin# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as 413200835Sedwin# local governments such as the Urumqi city government use both times in 414200835Sedwin# publications, referring to what is popularly called Xinjiang time as 415200835Sedwin# "Urumqi time."

Since "zonal" was not compatible with 97775267Swollman# any other timezone abbreviation, I felt that 'IST' was the way to go 97875267Swollman# and, indeed, it has received almost universal acceptance in timezone 97975267Swollman# settings in Israeli computers. 98075267Swollman# 98175267Swollman# In any case, I am happy to share timezone abbreviations with India, 98275267Swollman# high on my favorite-country list (and not only because my wife's 98375267Swollman# family is from India). 9842742Swollman 985158421Swollman# From Shanks & Pottenger: 9862742Swollman# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 9872742SwollmanRule Zion 1940 only - Jun 1 0:00 1:00 D 9882742SwollmanRule Zion 1942 1944 - Nov 1 0:00 0 S 9892742SwollmanRule Zion 1943 only - Apr 1 2:00 1:00 D 9902742SwollmanRule Zion 1944 only - Apr 1 0:00 1:00 D 9912742SwollmanRule Zion 1945 only - Apr 16 0:00 1:00 D 9922742SwollmanRule Zion 1945 only - Nov 1 2:00 0 S 9932742SwollmanRule Zion 1946 only - Apr 16 2:00 1:00 D 9942742SwollmanRule Zion 1946 only - Nov 1 0:00 0 S 9952742SwollmanRule Zion 1948 only - May 23 0:00 2:00 DD 9962742SwollmanRule Zion 1948 only - Sep 1 0:00 1:00 D 9972742SwollmanRule Zion 1948 1949 - Nov 1 2:00 0 S 9982742SwollmanRule Zion 1949 only - May 1 0:00 1:00 D 9992742SwollmanRule Zion 1950 only - Apr 16 0:00 1:00 D 10002742SwollmanRule Zion 1950 only - Sep 15 3:00 0 S 10012742SwollmanRule Zion 1951 only - Apr 1 0:00 1:00 D 10022742SwollmanRule Zion 1951 only - Nov 11 3:00 0 S 10032742SwollmanRule Zion 1952 only - Apr 20 2:00 1:00 D 10042742SwollmanRule Zion 1952 only - Oct 19 3:00 0 S 10052742SwollmanRule Zion 1953 only - Apr 12 2:00 1:00 D 10062742SwollmanRule Zion 1953 only - Sep 13 3:00 0 S 10072742SwollmanRule Zion 1954 only - Jun 13 0:00 1:00 D 10082742SwollmanRule Zion 1954 only - Sep 12 0:00 0 S 10092742SwollmanRule Zion 1955 only - Jun 11 2:00 1:00 D 10102742SwollmanRule Zion 1955 only - Sep 11 0:00 0 S 10112742SwollmanRule Zion 1956 only - Jun 3 0:00 1:00 D 10122742SwollmanRule Zion 1956 only - Sep 30 3:00 0 S 10132742SwollmanRule Zion 1957 only - Apr 29 2:00 1:00 D 10142742SwollmanRule Zion 1957 only - Sep 22 0:00 0 S 10152742SwollmanRule Zion 1974 only - Jul 7 0:00 1:00 D 10162742SwollmanRule Zion 1974 only - Oct 13 0:00 0 S 10172742SwollmanRule Zion 1975 only - Apr 20 0:00 1:00 D 10182742SwollmanRule Zion 1975 only - Aug 31 0:00 0 S 10192742SwollmanRule Zion 1985 only - Apr 14 0:00 1:00 D 10202742SwollmanRule Zion 1985 only - Sep 15 0:00 0 S 10212742SwollmanRule Zion 1986 only - May 18 0:00 1:00 D 10222742SwollmanRule Zion 1986 only - Sep 7 0:00 0 S 10232742SwollmanRule Zion 1987 only - Apr 15 0:00 1:00 D 10242742SwollmanRule Zion 1987 only - Sep 13 0:00 0 S 10252742SwollmanRule Zion 1988 only - Apr 9 0:00 1:00 D 10262742SwollmanRule Zion 1988 only - Sep 3 0:00 0 S 10272742Swollman 1028149514Swollman# From Ephraim Silverberg 1029149514Swollman# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22, 1030149514Swollman# and 2005-02-17): 103130711Swollman 10322742Swollman# According to the Office of the Secretary General of the Ministry of 10332742Swollman# Interior, there is NO set rule for Daylight-Savings/Standard time changes. 103443543Swollman# One thing is entrenched in law, however: that there must be at least 150 103543543Swollman# days of daylight savings time annually. From 1993-1998, the change to 103643543Swollman# daylight savings time was on a Friday morning from midnight IST to 103743543Swollman# 1 a.m IDT; up until 1998, the change back to standard time was on a 103843543Swollman# Saturday night from midnight daylight savings time to 11 p.m. standard 103943543Swollman# time. 1996 is an exception to this rule where the change back to standard 104043543Swollman# time took place on Sunday night instead of Saturday night to avoid 104164499Swollman# conflicts with the Jewish New Year.

Also, the "between the first Saturday 178193799Swollman# and Sunday of April" phrase, if taken literally, means that the 178293799Swollman# transition takes place at 00:00 on the first Sunday on or after 04-02. 178393799Swollman 1784114173Swollman# From Paul Eggert (2003-02-09): 1785114173Swollman# DAWN <http://www.dawn.com/2002/10/06/top13.htm> reported on 2002-10-05 1786114173Swollman# that 2002 DST ended that day at midnight.
