Hi All,
I've got a little problem where our servers are in PST but the customer
operates in Hawaii (-10 GMT). I believe I can just get the time for them by
doing something like
date(d H i, strtotime('now -2 hours') );
But here's the catch, how should I deal with day light savings ( DST) . In
hawaii they don't observer DST, but in Washington State we do.
We're on php 4.x so I can't use the date_default_timezone_set
http://us2.php.net/manual/en/function.date-default-timezone-set.php that
was added in PHP 5
Thanks, Mark
set TZ enviroment variable, it should point to a file containing
timezone information for Hawaii, for example:
putenv('TZ=/usr/share/zoneinfo/US/Hawaii');

Are you just displaying the time, or is this for submission in a
database?

Re: [PHP] Timezone and DST
I hate doing this, but you could use Javascript to use the date and time set
on the clients computer. You can't control how they have it set though.

You can use date( 'I' ) to determine whether or not your server is
currently in DST and subtract the appropriate number of hours
accordingly...
