Just looking into a failure in my test suite triggered by two timezone jumps within an hour: $ zdump -v America/Bahia_Banderas 2010 | grep 2010 America/Bahia_Banderas Sun Apr 4 06:59:59 2010 UTC = Sat Apr 3 23:59:59 2010 MST isdst=0 gmtoff=-25200 America/Bahia_Banderas Sun Apr 4 07:00:00 2010 UTC = Sun Apr 4 01:00:00 2010 CST isdst=0 gmtoff=-21600 America/Bahia_Banderas Sun Apr 4 07:59:59 2010 UTC = Sun Apr 4 01:59:59 2010 CST isdst=0 gmtoff=-21600 America/Bahia_Banderas Sun Apr 4 08:00:00 2010 UTC = Sun Apr 4 03:00:00 2010 CDT isdst=1 gmtoff=-18000 America/Bahia_Banderas Sun Oct 31 06:59:59 2010 UTC = Sun Oct 31 01:59:59 2010 CDT isdst=1 gmtoff=-18000 America/Bahia_Banderas Sun Oct 31 07:00:00 2010 UTC = Sun Oct 31 01:00:00 2010 CST isdst=0 gmtoff=-21600 Is this really correct, or should the timezone have jumped straight to CDT (-18000) at 0700 UTC? -- Stuart Bishop <stuart@stuartbishop.net> http://www.stuartbishop.net/
