-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, i'm not quite sure i understand the tzdata file format. I would like to add a rule to reflect this change, so would something like this work? # Venezuela # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Vzla 1964 max - Jan 1 0:00 0:30 S Rule Vzla 2007 max - Sep 24 0:00 0 - # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Caracas -4:27:44 - LMT 1890 -4:27:40 - CMT 1912 Feb 12 # Caracas Mean Time? -4:30 - VET 1964 # Venezuela Time -4:00 Vzla VET 2007 Sep 23 -4:30 Vzla VET Historically the change from UTC -4:30 to UTC -4 was in January 1964 (not 1965), skipping the very first 30 minutes of that year; how would a rule reflect this? This will end on Sep 23. From September 24 2007 when we are going back to UTC -4:30. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFG7+y7Uzw3EMm5P5wRAl6/AJwOpYCiNVO0y3D65skDtdn8emssIQCdGWRW +eLBB99tjjBZl1ywCGLTvcQ= =2kfj -----END PGP SIGNATURE-----
