 # James F. Smith writes in today's LA Times
 # </a>
 # * Sonora will continue to observe standard time.
-# * Border states including Baja California, Chihuahua, and Nuevo Leon
-#   will use US rules,
 # * 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
 #   the airport, banks, hospitals, and schools.
 #
-# For now we'll assume that the Federal District will bow to federal rules
-# and that border states and Durango will stick with US 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.
