 # From Peter Gradelski via Steffen Thorsen (2000-03-01):
 # We just checked with our San Paulo office and they say the government of
 # Argentina decided not to become one of the countries that go on or off DST.
 # So Buenos Aires should be -3 hours from GMT at all times.
 #
+# From Fabian L. Arce Jofre <farcejofre@bigfoot.com> (2000-04-04):
+# The law that claimed DST for Argentina was derogated by President Fernando
+# de la Rua on March 2, 2000, because it would make people spend more energy
+# in the winter time, rather than less.  The change took effect on March 3.
