dear TZ, I'm reporting an error in the Brazil timezone data I just downloaded from ftp://elsie.nci.nih.gov/pub/tzdata2001d.tar.gz according to the <a href="http://pcdsh01.on.br/HvInic01.htm">Brazilian official page</a> on the subject of DST: DST start: 2001-10-14T00:00:00 DST end: 2002-02-17T00:00:00 unfortunately I'm not familiar with the format of this file so I don't dare send you a corrected version; my best guess is that the corrections needed are: $ diff -u southamerica.orig southamerica --- southamerica.orig Wed Oct 10 09:51:50 2001 +++ southamerica Wed Oct 10 10:11:53 2001 @@ -414,8 +414,14 @@ # # For dates after mid-2002, the following rules are guesses # and are quite possibly wrong, but are more likely than no DST at all. -Rule Brazil 2000 max - Oct Sun>=8 0:00 1:00 S -Rule Brazil 2001 max - Feb Sun>=15 0:00 0 - +Rule Brazil 2000 only - Oct Sun>=15 0:00 1:00 S +Rule Brazil 2001 only - Feb Sun>=15 0:00 0 - +# +# From Otavio Exel <oexel@economatica.com.br> (2001-10-10): +# according to the <a href="http://pcdsh01.on.br/HvInic01.htm">Brazilian +# official page</a> on the subject of DST +Rule Brazil 2001 only - Oct Sun>=14 0:00 1:00 S +Rule Brazil 2002 only - Feb Sun>=17 0:00 0 - []s, -- Otavio Exel /<\oo/>\ oexel@economatica.com.br
