-# "Mar del Plata no quiere cambiar la hora" translates to
-# "Mar del Plata doesn't want to change the time"
-# (less definitive than "is not to").
+# This clearly breaks every time the 1st of March or October is a Sunday.
+#
+# IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd
+# Sunday of October and March.
+#
+# The problem is that the changes in the rest of the Provinces that did
+# change in 2007/2008, were made according to the Federal Law and Decrees
+# that did so on the 3rd Sunday of October and March.
+#
+# In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday
+# (October 11th) at 0:00.
+#
+# So I guess a new set of rules, besides "Arg", must be made and the last
+# America/Argentina/San_Luis entries should change to use these...
+#
+# I'm enclosing a patch that does what I say... regretfully, the San Luis
+# timezone must be called "WART/WARST" even when most of the time (like,
+# right now) WARST == ART... that is, since last Sunday, all the country
+# is using UTC-3, but in my patch, San Luis calls it "WARST" and the rest
+# of the country calls it "ART".
