+# Not everyone is happy with the results:

+# I don't really care how time is reckoned so long as there is some

+# A guy from our Mexico subsidiary finally found the Presidential Decree
+# outlining the timezone changes in Mexico.
+#
+# ------------- Begin Forwarded Message -------------
+#
+# I finally got my hands on the Official Presidential Decree that sets up the
+# rules for the DST changes. The rules are:
+#
+# 1. The country is divided in 3 timezones:
+# - Baja California Norte (the Mexico/BajaNorte TZ)
+# - Baja California Sur, Nayarit, Sinaloa and Sonora (the Mexico/BajaSur TZ)
+# - The rest of the country (the Mexico/General TZ)
+#
+# 2. From the first Sunday in April at 2:00 AM to the last Sunday in October
+# at 2:00 AM, the times in each zone are as follows:
+# BajaNorte: GMT+7
+# BajaSur: GMT+6
+# General: GMT+5
+#
+# 3. The rest of the year, the times are as follows:
+# BajaNorte: GMT+8
+# BajaSur: GMT+7
+# General: GMT+6
+#
+# The Decree was published in Mexico's Official Newspaper on January 4th.
+#
+# -------------- End Forwarded Message --------------
+# From Paul Eggert (1996-06-12):
+# For an English translation of the decree,
+# see ``Diario Oficial: Time Zone Changeover'',
+# <URL:http://mexico-travel.com/extra/timezone_eng.html> (1996-01-04).
