To be pedantic, FreeBSD 4.11 is correct and the others are wrong. If DST started at 2004-11-02 00:00 local time then you can't convert a local time of 2004-11-02 00:00:00 because that time doesn't exist - your local time goes 2004-11-01 23:59:59, 2004-11-02 01:00:00, 2004-11-02 01:00:01. server% TZ=':/usr/share/zoneinfo/America/Sao_Paulo' perl -e 'print scalar localtime 1099364400,"\n";' Tue Nov 2 01:00:00 2004 server% TZ=':/usr/share/zoneinfo/America/Sao_Paulo' perl -e 'print scalar localtime 1099364399,"\n";' Mon Nov 1 23:59:59 2004 server% -- Peter Jeremy
