Can you elaborate? /usr/share/zoneinfo contains the time zone information in files and subdirectories such as: GMT PST8PDT America/Chicago America/Los_Angeles Europe/London Europe/Rome and so on, for all the various time zones. You can use these names as strings in most time zone functions that accept a time zone. PHP knows about these; you'll find more info at http://us1.php.net/manual/en/timezones.php This doesn't help with the original question, finding out which time zone a user is in, but once you find out, using the canonical names will be useful without directly having to know if/when a particular zone is in DST or not. You should never (ever!) have to deal with the contents of these files; they contain binary data that is used in the system to deal with figuring out that sort of thing. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
