# This data is by no means authoritative; if you think you know better,

+# From Paul Eggert (2008-02-11):
+# I just now checked Google News for western news sources that talk
+# about China's single time zone, and couldn't find anything before 1986
+# talking about China being in one time zone. (That article was: Jim
+# Mann, "A clumsy embrace for another western custom: China on daylight
+# time--sort of", Los Angeles Times, 1986-05-05. By the way, this
+# article confirms the tz database's data claiming that China began
+# observing daylight saving time in 1986.
+#
+# From Thomas S. Mullaney (2008-02-11):
+# I think you're combining two subjects that need to treated
+# separately: daylight savings (which, you're correct, wasn't
+# implemented until the 1980s) and the unified time zone centered near
+# Beijing (which was implemented in 1949). Briefly, there was also a
+# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was
+# ceased, and the second eventually recognized (again, in the 1980s).
+#
+# From Paul Eggert (2008-06-30):
+# There seems to be a good chance China switched to a single time zone in 1949
+# rather than in 1980 as Shanks & Pottenger have it, but we don't have a
+# reliable documentary source saying so yet, so for now we still go with
+# Shanks & Pottenger.

# http://www.mme.gov.br/site/news/detail.do;jsessionid=BBA06811AFCAAC28F0285210913513DA?newsId=13975
+# 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:

+# </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 Alex Krivenyshev (2008-06-24):
+# This is a quick reference page for New and Old Brazil Time Zones map.

+#
+# - 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
