# Iraq

+# From Jonathan Lennox <lennox@cs.columbia.edu> (2000-06-12):
+# An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
+# the U.S. edition) on the Iraqi Kurds contains a paragraph:
+# "The three northern provinces ... switched their clocks this spring and
+# are an hour ahead of Baghdad."
+#
+# But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
+# In the past, some Kurdish nationalists, as a protest to the Iraqi
+# Government, did not adhere to daylight saving time. They referred
+# to daylight saving as Saddam time. But, as of today, the time zone
+# in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
+#
+# So we'll ignore the Economist's claim.

-# From Guy Harris:
-# Rules are from the Official Airline Guide, Worldwide Edition, for 1987.
-# Rules [before] 1987 are unknown.
-# The comments in the OAG say "Only Ensenada, Mexicale, San Felipe and Tijuana
-# observe DST." This is presumably Baja California Norte, above 28th parallel,
-# as listed there; [there is also] "Baja California Sur and N. Pacific
-# Coast (States of Sinaloa and Sonora)."
-
-# From Bob Devine (1988-01-28):
-# The Federal District (where Mexico City is) has observed [DST] several
-# times but not recently.
+# 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:
#
-# I don't where to draw the line in the North Baja area. 28th latitude
-# sounds good -- but it may be higher (how far [d]o radio stations from
-# San Diego affect culture?).
+# 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.
#
-# The dates of DST probably go back to 1981. The rules are the same as
-# US's. This is going to be a headache for US presidential electi[o]n years!
