Note the "0000060 0004" above and the "0000060 0000" below. The number in question is the index into the zone abbreviation characters which are "LMT\0CCT\0"; the difference is why we're seeing "CCT" (the correct behavior) on elsie and "LMT" (the worng behavior) on your system; it's also why the zgress test worked here on elsie. --ado -----Original Message----- From: Robbin Kawabata [mailto:Robbin.Kawabata@eng.sun.com] Sent: Friday, March 17, 2006 5:11 PM To: tz@elsie.nci.nih.gov; eggert@CS.UCLA.EDU; Olson, Arthur David (NIH/NCI) [E]; olsona@elsie.nci.nih.gov Cc: robbin.kawabata@sun.com Subject: tz behavior difference TZif vs. TZif2 ...
