Display time for two different time zones

[msi3753]

I have looked through the php manual, and I honestly can't figure out the answer to this (I really did try). I want to display EST (Eastern Standard Time) and JST (Japan Standard Time) on a webpage that is hosted in CST (Central Stardard Time). Can someone please help me with some code that will accomplish this? Thank you 🙂 .

phpbuilder (fancy that!) has a nice article on timezones, give it a read 😉

That helped, but it wasn't the clear solution I was hoping for. Thank you for the effort though.

With a little more searching, I found a simple solution. I hope this helps someone out there.

/*
$current should be the timezone on the
current machine, $target is the timezone
you want to calculate.  Both should be in
hours.  For example, GMT -05:00 should
be -5.  GMT +12:00 should be 12.  You can
use the returned timestamp with the date
function.
ex: echo date('r', zonechange(-5, 10));
would echo the date for a +10:00
timezone on a machine in -05:00.
*/
function zonechange ($current, $target) {
   $current = -1 * $current;
   $zonedate = mktime(date('G'), date('i'), date('s'), date('n'),
   date('j'), date('Y'), 1) + (($current + $target) * 3600);
   return $zonedate;
}
