# Mexico
-# 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.
+# 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>.
+#
+# 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.

+#
+# 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):
+# For now, we'll just record the time in Stanley, since we have no
+# better info.
