+# From Paul Schulze (2008-06-24):
+# ...by law number 11.662 of April 24, 2008 (published in the "Diario
+# Oficial da Uniao"...) in Brazil there are changes in the timezones,
+# effective today (00:00am at June 24, 2008) as follows:
+#
+# a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the
+# part of the Amazonas state that had this timezone now being put to the
+# timezone UTC+4
+# b) The whole Para state now is put at timezone UTC+3, instead of just
+# part of it, as was before.
+#
+# This change follows a proposal of senator Tiao Viana of Acre state, that
+# proposed it due to concerns about open television channels displaying
+# programs inappropriate to youths in the states that had the timezone
+# UTC+5 too early in the night. In the occasion, some more corrections
+# were proposed, trying to unify the timezones of any given state. This
+# change modifies timezone rules defined in decree 2.784 of 18 June,
+# 1913.

+# From Rodrigo Severo (2008-06-24):

+# </a>
+#
+# As a result of the above Decree I believe the America/Rio_Branco
+# timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
+# be created to represent the the west side of the Para State. I
+# suggest this new timezone be called Santarem as the most
+# important/populated city in the affected area.
+#
+# This new timezone would be the same as the Rio_Branco timezone up to
+# the 2008/06/24 change which would be to UTC-3 instead of UTC-4.

+# From Steffen Thorsen (2008-08-29):
+# As announced by the government and many newspapers in Brazil late
+# yesterday, Brazil will start DST on 2008-10-19 (need to change rule) and
+# it will end on 2009-02-15 (current rule for Brazil is fine). Based on
