+# I coined "IST/IDT" circa 1988.  Until then there were three

+# 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,

-# 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:
-#
-# 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.

+# 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.

+# From Paul Eggert (2001-03-05):
+# 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
+# name or contents should be.

+# From Rives McDow (2001-02-13):
+#
+# I have communicated several times with people there, and the last
+# time I had communications that was helpful was in 1998.  Here is
+# what was said then:
+#
+# "The general rule was that Stanley used daylight saving and the Camp
+# did not. However for various reasons many people in the Camp have
+# started to use daylight saving (known locally as 'Stanley Time')
+# There is no rule as to who uses daylight saving - it is a matter of
+# personal choice and so it is impossible to draw a map showing who
+# uses it and who does not. Any list would be out of date as soon as
+# it was produced. This year daylight saving ended on April 18/19th
+# and started again on September 12/13th.  I do not know what the rule
+# is, but can find out if you like.  We do not change at the same time
+# as UK or Chile."
+#
+# I did have in my notes that the rule was "Second Saturday in Sep at
+# 0:00 until third Saturday in Apr at 0:00".  I think that this does
+# not agree in some cases with Shanks; is this true?
+#
+# 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):
