Hi, I apologize for not replying sooner. Thanks everybody for your help. I think I can pin point this bug to Firefox not accounting for _double_ summer time.

I'd like to ask a question regarding Europe/Zagreb timezone for years 1941-1945. I actually reported a bug in Firefox but that turned out not to be the case. I'll leave url just in case you need more information: https://bugzilla.mozilla.org/show_bug.cgi?id=704486
You can see the transitions for Europe/Zagreb between 1940 and 1946 (according to the tz data installed on your system) like this :- zdump -v -c1940,1946 Europe/Zagreb For each transition, that will show the time (UTC and local) one second before and at the transition. In between those transitions, the offset and time zone abbreviation remain the same. That should help you isolate whether you have a problem with the tz data installed on your system, or with Firefox's interpretation of tz data. If the offset in Firefox disagrees with the offset in zdump and Firefox is supposed to use tz data then Firefox has a bug. PS: The "Europe/Zagreb" argument to zdump is a time zone name (like you would put in $TZ) not a file name. -- ___________________________________________________________________________ David Keegel <djk@cyber.com.au> Cyber IT Solutions Pty.
