 # Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00:

+# 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):
+# Just correcting the URL:
+# 
+# https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=3Ddo&secao=3D1&pagina=3D1&data=3D25/04/2008
+# 
+#
+# 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 Alex Krivenyshev (2008-06-24):
+# This is a quick reference page for New and Old Brazil Time Zones map.
+# 
+# http://www.worldtimezone.com/brazil-time-new-old.php
+# 
+#
+# - 4 time zones replaced by 3 time zones-eliminating time zone UTC- 05
+# (state Acre and the part of the Amazonas will be UTC/GMT- 04) - western
+# part of Par state is moving to one timezone UTC- 03 (from UTC -04).
