# daylight saving time citing lack of economic benefits and health
# complications coupled with a decrease in productivity.
#
# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
# ... what happened was that the former Kazakhstan Eastern time zone
# was "blended" with the Central zone.  Therefore, Kazakhstan now has
# two time zones, and difference between them is one hour.  The zone
# closer to UTC is the former Western zone (probably still called the
# same), encompassing four provinces in the west: Aqtobe, Atyrau,
# Mangghystau, and West Kazakhstan.  The other zone encompasses
# everything else....  I guess that would make Kazakhstan time zones
# de jure UTC+5 and UTC+6 respectively.

# Mongolia

# Shanks says that Mongolia has three time zones, but usno1995 and the CIA map
# Standard Time Zones of the World (1997-01)
# both say that it has just one.

# From Oscar van Vlijmen (1999-12-11):
# <a href="http://www.mongoliatourism.gov.mn/general.htm">
# General Information Mongolia
# </a> (1999-09)
# "Time: Mongolia has two time zones. Three westernmost provinces of
# Bayan-Ulgii, Uvs, and Hovd are one hour earlier than the capital city, and
# the rest of the country follows the Ulaanbaatar time, which is UTC/GMT plus
# eight hours."

# From Rives McDow (1999-12-13):
# Mongolia discontinued the use of daylight savings time in 1999; 1998
# being the last year it was implemented.  The dates of implementation I am
# unsure of, but most probably it was similar to Russia, except for the time
# of implementation may have been different....
# Some maps in the past have indicated that there was an additional time
# zone in the eastern part of Mongolia, including the provinces of Dornod,
# Suhbaatar, and possibly Khentij.

# From Paul Eggert (1999-12-15):
# Naming and spelling is tricky in Mongolia.
# We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone;
# the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us,
# and sometimes Jirgalanta (with variant spellings), but the name Hovd
# is good enough for our purposes.

# From Rives McDow (2001-05-13):
# In addition to Mongolia starting daylight savings as reported earlier
# (adopted DST on 2001-04-27 02:00 local time, ending 2001-09-28),
# there are three time zones.
#
# Provinces [at 7:00]: Bayan-ulgii, Uvs, Khovd, Zavkhan, Govi-Altai
# Provinces [at 8:00]: Khovsgol, Bulgan, Arkhangai, Khentii, Tov,
#	Bayankhongor, Ovorkhangai, Dundgovi, Dornogovi, Omnogovi
# Provinces [at 9:00]: Dornod, Sukhbaatar
#
# [The province of Selenge is omitted from the above lists.]

# From Ganbold Ts., Ulaanbaatar (2004-04-17):
# Daylight saving occurs at 02:00 local time last Saturday of March.
# It will change back to normal at 02:00 local time last Saturday of
# September.... As I remember this rule was changed in 2001.
#
# From Paul Eggert (2004-04-17):
# For now, assume Rives McDow's informant got confused about Friday vs
# Saturday, and that his 2001 dates should have 1 added to them.

# From Paul Eggert (2005-07-26):
# We have wildly conflicting information about Mongolia's time zones.
# Bill Bonnet (2005-05-19) reports that the US Embassy in Ulaanbaatar says
# there is only one time zone and that DST is observed, citing Microsoft
# Windows XP as the source.  Risto Nykanen (2005-05-16) reports that
# travelmongolia.org says there are two time zones (UTC+7, UTC+8) with no DST.
# Oscar van Vlijmen (2005-05-20) reports that the Mongolian Embassy in
# Washington, DC says there are two time zones, with DST observed.
# He also found
# <http://ubpost.mongolnews.mn/index.php?subaction=showcomments&id=1111634894&archive=&start_from=&ucat=1&>
# which also says that there is DST, and which has a comment by "Toddius"
# (2005-03-31 06:05 +0700) saying "Mongolia actually has 3.5 time zones.
# The West (OLGII) is +7 GMT, most of the country is ULAT is +8 GMT
# and some Eastern provinces are +9 GMT but Sukhbaatar Aimag is SUHK +8.5 GMT.
# The SUKH timezone is new this year, it is one of the few things the
# parliament passed during the tumultuous winter session."
# For now, let's ignore this information, until we have more confirmation.
