So let him specify the area in which he is in, then you can use the correct timezone identifier for it. This is what the new code now allows you to do, which should make things much easier for you. I'll see if I can get the list of supported identifiers in the manual, as for PHP 5.1.0 the previously mentioned timezone_identifiers_list() is not enabled here yet. For information on how to use things, see this presentation: http://derickrethans.nl/files/time-ac2005.pdf > The FIRST problem I had was STOPPING the display from being offset by the > SERVER daylight saving setting! > There is absolutely no reason that date() should supply anything other than > the current UTC time. It is the only thing that is actually RIGHT! gmdate() is for that, date() should always show a local time. The new code (which is unfortunately not enabled), allows you do do all kinds of timezone manipulation. Feel free to test it by setting your CFLAGS to -DEXPERIMENTAL_DATE_SUPPORT and use the new functions following the examples from the presentation. regards, Derick -- Derick Rethans http://derickrethans.nl | http://ez.no | http://xdebug.org -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
