The government of the Xinjiang 410200835Sedwin# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as 411200835Sedwin# local governments such as the Urumqi city government use both times in 412200835Sedwin# publications, referring to what is popularly called Xinjiang time as 413200835Sedwin# "Urumqi time."

Since "zonal" was not compatible with 99875267Swollman# any other timezone abbreviation, I felt that 'IST' was the way to go 99975267Swollman# and, indeed, it has received almost universal acceptance in timezone 100075267Swollman# settings in Israeli computers. 100175267Swollman# 100275267Swollman# In any case, I am happy to share timezone abbreviations with India, 100375267Swollman# high on my favorite-country list (and not only because my wife's 100475267Swollman# family is from India). 10052742Swollman 1006158421Swollman# From Shanks & Pottenger: 10072742Swollman# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 10082742SwollmanRule Zion 1940 only - Jun 1 0:00 1:00 D 10092742SwollmanRule Zion 1942 1944 - Nov 1 0:00 0 S 10102742SwollmanRule Zion 1943 only - Apr 1 2:00 1:00 D 10112742SwollmanRule Zion 1944 only - Apr 1 0:00 1:00 D 10122742SwollmanRule Zion 1945 only - Apr 16 0:00 1:00 D 10132742SwollmanRule Zion 1945 only - Nov 1 2:00 0 S 10142742SwollmanRule Zion 1946 only - Apr 16 2:00 1:00 D 10152742SwollmanRule Zion 1946 only - Nov 1 0:00 0 S 10162742SwollmanRule Zion 1948 only - May 23 0:00 2:00 DD 10172742SwollmanRule Zion 1948 only - Sep 1 0:00 1:00 D 10182742SwollmanRule Zion 1948 1949 - Nov 1 2:00 0 S 10192742SwollmanRule Zion 1949 only - May 1 0:00 1:00 D 10202742SwollmanRule Zion 1950 only - Apr 16 0:00 1:00 D 10212742SwollmanRule Zion 1950 only - Sep 15 3:00 0 S 10222742SwollmanRule Zion 1951 only - Apr 1 0:00 1:00 D 10232742SwollmanRule Zion 1951 only - Nov 11 3:00 0 S 10242742SwollmanRule Zion 1952 only - Apr 20 2:00 1:00 D 10252742SwollmanRule Zion 1952 only - Oct 19 3:00 0 S 10262742SwollmanRule Zion 1953 only - Apr 12 2:00 1:00 D 10272742SwollmanRule Zion 1953 only - Sep 13 3:00 0 S 10282742SwollmanRule Zion 1954 only - Jun 13 0:00 1:00 D 10292742SwollmanRule Zion 1954 only - Sep 12 0:00 0 S 10302742SwollmanRule Zion 1955 only - Jun 11 2:00 1:00 D 10312742SwollmanRule Zion 1955 only - Sep 11 0:00 0 S 10322742SwollmanRule Zion 1956 only - Jun 3 0:00 1:00 D 10332742SwollmanRule Zion 1956 only - Sep 30 3:00 0 S 10342742SwollmanRule Zion 1957 only - Apr 29 2:00 1:00 D 10352742SwollmanRule Zion 1957 only - Sep 22 0:00 0 S 10362742SwollmanRule Zion 1974 only - Jul 7 0:00 1:00 D 10372742SwollmanRule Zion 1974 only - Oct 13 0:00 0 S 10382742SwollmanRule Zion 1975 only - Apr 20 0:00 1:00 D 10392742SwollmanRule Zion 1975 only - Aug 31 0:00 0 S 10402742SwollmanRule Zion 1985 only - Apr 14 0:00 1:00 D 10412742SwollmanRule Zion 1985 only - Sep 15 0:00 0 S 10422742SwollmanRule Zion 1986 only - May 18 0:00 1:00 D 10432742SwollmanRule Zion 1986 only - Sep 7 0:00 0 S 10442742SwollmanRule Zion 1987 only - Apr 15 0:00 1:00 D 10452742SwollmanRule Zion 1987 only - Sep 13 0:00 0 S 10462742SwollmanRule Zion 1988 only - Apr 9 0:00 1:00 D 10472742SwollmanRule Zion 1988 only - Sep 3 0:00 0 S 10482742Swollman 1049149514Swollman# From Ephraim Silverberg 1050149514Swollman# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22, 1051149514Swollman# and 2005-02-17): 105230711Swollman 10532742Swollman# According to the Office of the Secretary General of the Ministry of 10542742Swollman# Interior, there is NO set rule for Daylight-Savings/Standard time changes. 105543543Swollman# One thing is entrenched in law, however: that there must be at least 150 105643543Swollman# days of daylight savings time annually. From 1993-1998, the change to 105743543Swollman# daylight savings time was on a Friday morning from midnight IST to 105843543Swollman# 1 a.m IDT; up until 1998, the change back to standard time was on a 105943543Swollman# Saturday night from midnight daylight savings time to 11 p.m. standard 106043543Swollman# time. 1996 is an exception to this rule where the change back to standard 106143543Swollman# time took place on Sunday night instead of Saturday night to avoid 106264499Swollman# conflicts with the Jewish New Year.
