Here's an updated version of the patch to fix the currently-incorrect
clock settings we have for several provinces in Argentina; it
incorporates the recent messages from Mariano Absatz and Gwillim Law
(thanks!).

+# midnight Monday May 31st. (that is, the night between 05/31 and 06/01).
+# Apparently, all nine provinces would go back to UTC-03:00 at the same

+# From Mariano Absatz (2004-06-14):
+# ... this weekend, the Province of Tucuman decided it'd go back to UTC-03:00
+# yesterday midnight (that is, at 24:00 Saturday 12th), since the people's
+# annoyance with the change is much higher than the power savings obtained....

+#     "The time change in Tierra del Fuego was a conflicted decision from
+#   the start.  The government had decreed that the measure would take
+#   effect on June 1, but a normative error forced the new time to begin
+#   three days earlier, from a Saturday to a Sunday....
+# Our understanding was that the change was originally scheduled to take place
+# on June 1 at 00:00 in Chubut, Santa Cruz, Tierra del Fuego (and some other
+# provinces).  Sunday was May 30, only two days earlier.  So the article
+# contains a contradiction.  I would give more credence to the Saturday/Sunday
+# date than the "three days earlier" phrase, and conclude that Tierra del
+# Fuego set its clocks back at 2004-05-30 00:00.
