Subject: Time zone changes due to Brazilian Summer Time
Dear sirs,
Below are the patches (with full comments) for adjusting zone
information for South America, due to Brazilian changing of beginning
and ending dates for adoption of summer time. Patches can be applied to
version 7.36 (as available from ftp://elsie.nci.nih.gov at 2000/10/04
00:00 GMT), and they are in unified diff format.
I am also sending the full altered file, as a GNU-zip compressed
attachment.
Regards,
Paulo A. P. Pires -- p at ppires.org

+# Brazil changed rules once again. Late decree with poor announcement
+# (even some telephone companies had their services one hour ahead of legal
+# for a short time).
+# According to sources in the Research Group on Energy, from the Institute
of
+# Economics of the Federal University of Rio de Janeiro, initial and final
+# summer time dates were not originally supposed to change from previous
year,
+# but people in northern states don't like summer time (for the obvious
reason
+# that is not as effective, but rather uncomfortable, near the Equator
line).
+# Decree <a href="http://pcdsh01.on.br/DEC3592.htm">3592</A> (2000/09/06)
lists
+# the following states to obey summer time: RS, SC, PR, SP, RJ, ES, MG, GO,
+# MT, MS, TO, BA, SE, AL, PE, RN, CE, PI, MA, RR and DF.
