# East Timor
# From Joao Carrascalao, brother of the former governor of East Timor, in
# <a href="http://etan.org/et99c/december/26-31/30ETMAY.htm">
# East Timor may be late for its millennium
# </a> (1999-12-26/31):
# Portugal tried to change the time forward in 1974 because the sun
# rises too early but the suggestion raised a lot of problems with the
# Timorese and I still don't think it would work today because it
# conflicts with their way of life.
# From Paul Eggert (2000-12-04):
# We don't have any record of the above attempt.
# Most likely our records are incomplete, but we have no better data.

# which will be permanent, with no seasonal adjustment, will happen at

#
# I coined "IST/IDT" circa 1988. Until then there were three
# different abbreviations in use:
#
# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
# EEST Eastern Europe Standard Time [used by almost everyone else]
#
# Since timezones should be called by country and not capital cities,
# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
# EEST was equally unacceptable. Since "zonal" was not compatible with
# any other timezone abbreviation, I felt that 'IST' was the way to go
# and, indeed, it has received almost universal acceptance in timezone
# settings in Israeli computers.
#
# In any case, I am happy to share timezone abbreviations with India,
# high on my favorite-country list (and not only because my wife's
# family is from India).

# Gwillim Law reports this source for daylight saving time in Mexico:
# <a href="http://www.spin.com.mx/verano/">
# Daylight saving time * SPIN-Internet (in Spanish)
# </a>
# Law (2000-03-09) translates it as follows:
# From Paul Eggert (2001-03-05):
# The Investigation and Analysis Service of the
# Mexican Library of Congress (MLoC) has published a
# <a href="http://www.cddhcu.gob.mx/bibliot/publica/inveyana/polisoc/horver/">
# history of Mexican local time (in Spanish)
# </a>.
#
# Standard time effective in Mexico takes its origin in the
# presidential decree of April 24, 1942. The time of the 120th
# meridian applies to the state of Baja California; of the 105th
# meridian to the states of Baja California Sur, Sonora, Sinaloa, and
# Nayarit; and the time of the 90th meridian to the rest of the
# country.
#
# In the country, there have been several attempts made to adapt
# standard time with the object of arriving at a better use of
# daylight for social and economic activities. In December, 1981 a
# permanent time zone was decreed for the states of Campeche, Yucatan,
# and Quintana Roo, displacing them from the 90th to the 75th
# meridian. This disposition was annulled on December 2, 1982.
#
# In 1988 a Summer Time was established for the states of Tamaulipas,
# Nuevo Leon, Coahuila, and Durango, which meant that from the first
# Sunday in April to the last [Sunday] of October those states
# displaced their time from the 90th to the 75th meridian. That
# disposition lasted for one year.
# Here are the discrepancies between Shanks and the MLoC.
# (In all cases we go with the MLoC.)
# Shanks reports that Baja was at -8:00 in 1922/1923.
# Shanks says the 1930 transition in Baja was 1930-11-16.
# Shanks reports no DST during summer 1931.
# Shanks reports a transition at 1032-03-30 23:00, not 1932-04-01.
# Shanks does not report transitions for Baja in 1945 or 1948.
# Shanks reports southern Mexico transitions on 1981-12-01, not 12-23.
# Shanks says Quintana Roo switched to -6:00 on 1982-12-02, and to -5:00
# on 1997-10-26 at 02:00.
# From Gwillim Law (2001-02-20):
# There are some other discrepancies between the Decrees page and the
# tz database. I think they can best be explained by supposing that
# the researchers who prepared the Decrees page failed to find some of
# the relevant documents.
# From Paul Eggert (2000-07-26):
# Shanks gives 1942-04-01 instead of 1942-04-24, and omits the 1981

# </a>
# * Sonora will continue to observe standard time.
# * Last week Mexico City's mayor Andres Manuel Lopez Obrador decreed that
# the Federal District will not adopt DST.
# * 4 of 16 district leaders announced they'll ignore the decree.
# * The decree does not affect federal-controlled facilities including

# For now we'll assume that the Federal District will bow to federal rules.
# From Jesper Norgaard (2001-04-01):
# I found some references to the Mexican application of daylight
# saving, which modifies what I had already sent you, stating earlier
# that a number of northern Mexican states would go on daylight
# saving. The modification reverts this to only cover Baja California
# (Norte), while all other states (except Sonora, who has no daylight
# saving all year) will follow the original decree of president
# Vicente Fox, starting daylight saving May 6, 2001 and ending
# September 30, 2001.

# Formerly there was an America/Ensenada zone, which differed from
# America/Tijuana only in that it did not observe DST from 1976
# through 1995. This was as per Shanks. However, Guy Harris reports
# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
# Tijuana observe DST," which contradicts Shanks but does imply that
# DST-observance was a town-by-town matter back then. This concerns
# data after 1970 so most likely there should be at least one Zone
# other than America/Tijuana for Baja, but it's not clear yet what its

# Also, there is no mention in the list that some areas in the
# Falklands do not use DST. I have found in my communications there
# that these areas are on the western half of East Falkland and all of
# West Falkland. Stanley is the only place that consistently observes
# DST. Again, as in other places in the world, the farmers don't like
# it. West Falkland is almost entirely sheep farmers.
#
# I know one lady there that keeps a list of which farm keeps DST and
# which doesn't each year. She runs a shop in Stanley, and says that
# the list changes each year. She uses it to communicate to her
# customers, catching them when they are home for lunch or dinner.
# From Paul Eggert (2001-03-05):
# For now, we'll just record the time in Stanley, since we have no
# better info.
