Daylight savings transitions are controlled by /etc/localtime which is either a copy of, or a link to, one of the files in /usr/share/zoneinfo This is a binary file containing a converted form of data from (in your case) /usr/src/share/zoneinfo/southamerica. The latter file includes the following: # Decree 3,592 (2000-09-06) # adopted by the same states as before. # Decree 3,630 (2000-10-13) # repeals DST in PE and RR, effective 2000-10-15 00:00. # Decree 3,632 (2000-10-17) # repeals DST in SE, AL, PB, RN, CE, PI and MA, effective 2000-10-22 00:00. # Decree 3,916 # (2001-09-13) reestablishes DST in AL, CE, MA, PB, PE, PI, RN, SE. # # The latest decree listed above says that the following states observe DST: # AL, BA, CE, DF, ES, GO, MA, MG, MS, MT, # PB, PE, PI, PR, RJ, RN, RS, SC, SE, SP, TO. # # 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 - Which indicates that DST starts on the first Sunday on or after 8th October. See tzfile(5), zdump(8) and zic(8) for complete details. The top of the file states: # This data is by no means authoritative; if you think you know better, # go ahead and edit the file (and please send any changes to # tz@elsie.nci.nih.gov for general use in the future). (and you should raise a FreeBSD PR containing the same information). Peter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
