470# First Deputy to the President - Hassan Habibi

472# From personal experience, that agrees with what has been followed
473# for at least the last 5 years. Before that, for a few years, the
474# date used was the first Thursday night of Farvardin and the last
475# Thursday night of Shahrivar, but I can't give exact dates....
476# I have also changed the abbreviations to what is considered correct
477# here in Iran, IRST for regular time and IRDT for daylight saving time.
478#
479# From Roozbeh Pournader (2005-04-05):
480# The text of the Iranian law, in effect since 1925, clearly mentions
481# that the true solar year is the measure, and there is no arithmetic
482# leap year calculation involved. There has never been any serious
483# plan to change that law....
484#
485# From Paul Eggert (2005-04-05):
486# Go with Shanks before September 1991, and with Pournader thereafter.
487# I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
488# stopping after 2037 when 32-bit time_t's overflow.
489# That cal-persia used Birashk's approximation, which disagrees with the solar
490# calendar predictions for the year 2025, so I corrected those dates by hand.
491#
492# From Oscar van Vlijmen (2005-03-30), writing about future
493# discrepancies between cal-persia and the Iranian calendar:
494# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
495# the vernal equinox and that gets so close to 12:00 some local
496# Iranian time that the definition of the correct location needs to be
497# known exactly, amongst other factors. 2157 is even closer:
498# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
499# no interpretation problem whatsoever. By the way, another instant
500# in the near future where there will be a discrepancy between
501# arithmetical and astronomical Iranian calendars will be in 2058:
502# vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
503# Reingold's/Dershowitz' calculator gives correctly the Gregorian date
504# 2058-03-21 for 1 Farvardin 1437 (astronomical).

959# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
960# ... what happened was that the former Kazakhstan Eastern time zone
961# was "blended" with the Central zone. Therefore, Kazakhstan now has
962# two time zones, and difference between them is one hour. The zone
963# closer to UTC is the former Western zone (probably still called the

965# Mangghystau, and West Kazakhstan. The other zone encompasses

492# From Oscar van Vlijmen (2005-03-30), writing about future

494# For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
495# the vernal equinox and that gets so close to 12:00 some local
496# Iranian time that the definition of the correct location needs to be
497# known exactly, amongst other factors. 2157 is even closer:
498# 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
499# no interpretation problem whatsoever. By the way, another instant
500# in the near future where there will be a discrepancy between
501# arithmetical and astronomical Iranian calendars will be in 2058:

937# stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
938# and Aqtau (formerly Shevchenko) are the largest cities in their zones.
939# Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time

943# German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses

945# Go with Shanks, who has them always using RussiaAsia rules.
946# Also go with the following claims of Shanks:
947#
948# - Kazakhstan did not observe DST in 1991.
949# - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.

955# The Government of Kazakhstan passed a resolution March 15 abolishing

959# From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
960# ... what happened was that the former Kazakhstan Eastern time zone
961# was "blended" with the Central zone. Therefore, Kazakhstan now has
962# two time zones, and difference between them is one hour. The zone
963# closer to UTC is the former Western zone (probably still called the
964# same), encompassing four provinces in the west: Aqtobe, Atyrau,
965# Mangghystau, and West Kazakhstan. The other zone encompasses
966# everything else.... I guess that would make Kazakhstan time zones

1213# We have wildly conflicting information about Mongolia's time zones.
1214# Bill Bonnet (2005-05-19) reports that the US Embassy in Ulaanbaatar says
1215# there is only one time zone and that DST is observed, citing Microsoft
1216# Windows XP as the source. Risto Nykanen (2005-05-16) reports that
1217# travelmongolia.org says there are two time zones (UTC+7, UTC+8) with no DST.
1218# Oscar van Vlijmen (2005-05-20) reports that the Mongolian Embassy in
1219# Washington, DC says there are two time zones, with DST observed.
1220# He also found

1222# which also says that there is DST, and which has a comment by "Toddius"
1223# (2005-03-31 06:05 +0700) saying "Mongolia actually has 3.5 time zones.
1224# The West (OLGII) is +7 GMT, most of the country is ULAT is +8 GMT
1225# and some Eastern provinces are +9 GMT but Sukhbaatar Aimag is SUHK +8.5 GMT.
1226# The SUKH timezone is new this year, it is one of the few things the
1227# parliament passed during the tumultuous winter session."
1228# For now, let's ignore this information, until we have more confirmation.
