+# as earlier as upcoming Monday January 21, 2008 or February 2008:

+# The page of the San Luis provincial government
+# 
+# http://www.sanluis.gov.ar/notas.asp?idCanal=0&id=22812
+# 
+# confirms what Alex Krivenyshev has earlier sent to the tz
+# emailing list about that San Luis plans to return to standard
+# time much earlier than the rest of the country. It also
+# confirms that upon request the provinces San Juan and Mendoza 
+# 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
+# independent changes in the southamerica file of San Luis in
+# 1990 and 1991 which has not been confirmed).
+
+# From Jesper Norgaard Welen (2008-01-25):
+# Unfortunately the below page has become defunct, about the San Luis
+# time change. Perhaps because it now is part of a group of pages "Most
+# important pages of 2008."
+#
+# You can use
+# 
+# http://www.sanluis.gov.ar/notas.asp?idCanal=8141&id=22834
+# 
+# instead it seems. Or use "Buscador" from the main page of the San Luis
+# 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).
+
+# From Arthur David Olson (2008-03-15):
+# Until there's better information, asssume San Luis was like San Juan
+# rather than Mendoza (since San Juan has a simpler DST history).
