874# General Information Mongolia

876# "Time: Mongolia has two time zones. Three westernmost provinces of
877# Bayan-Ulgii, Uvs, and Hovd are one hour earlier than the capital city, and
878# the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus

881# From Rives McDow (1999-12-13):
882# Mongolia discontinued the use of daylight savings time in 1999; 1998
883# being the last year it was implemented. The dates of implementation I am
884# unsure of, but most probably it was similar to Russia, except for the time
885# of implementation may have been different....
886# Some maps in the past have indicated that there was an additional time
887# zone in the eastern part of Mongolia, including the provinces of Dornod,
888# Suhbaatar, and possibly Khentij.
889
890# From Paul Eggert (1999-12-15):
891# For now, we'll comment out the east zone (Choybalsan)
892# and use Shanks's and the IATA's data for the daylight-saving rules.
893# Naming and spelling is tricky in Mongolia.
894# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
895# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
896# and sometimes Jirgalanta (with variant spellings), but the name Hovd
897# is good enough for our purposes.
