-# <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.

+# America/Tijuana only in that it did not observe DST from 1976
+# through 1995. This was as per Shanks. However, Guy Harris reports

+# I have communicated several times with people there, and the last

+#
+# "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

+# uses it and who does not. Any list would be out of date as soon as

+# 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

+#
+# 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

+# I know one lady there that keeps a list of which farm keeps DST and
