+# refused to follow San Luis in this change. 
+# 
+# The change is supposed to take place Monday the 21.st at 0:00
+# hours. As far as I understand it if this goes ahead, we need
+# a new timezone for San Luis (although there are also documented

+# government, and fill in "huso" and click OK, and you will get 3 pages
+# from which the first one is identical to the above.

+# From Mariano Absatz (2008-01-28):
+# I can confirm that the Province of San Luis (and so far only that
+# province) decided to go back to UTC-3 effective midnight Jan 20th 2008
+# (that is, Monday 21st at 0:00 is the time the clocks were delayed back
+# 1 hour), and they intend to keep UTC-3 as their timezone all year round
+# (that is, unless they change their mind any minute now).
+#
+# So we'll have to add yet another city to 'southamerica' (I think San
+# Luis city is the mos populated city in the Province, so it'd be
+# America/Argentina/San_Luis... of course I can't remember if San Luis's
+# history of particular changes goes along with Mendoza or San Juan :-(
+# (I only remember not being able to collect hard facts about San Luis
+# back in 2004, when these provinces changed to UTC-4 for a few days, I
+# mailed them personally and never got an answer).
