Adding n hours to GMT, help pls

[Anon]

Hi
I am working on a site that will be hosted on a server in the US, but it's audience is primarily Australian. So I want to display the date and time items were posted etc in Australian time.
What is the best way to accomplish this.
I know I can use someting like:
gmstrftime ()
to get GMT for the current time on the server. But how do I add the 10 or 11 hours difference to reflect the current time in Australia?

Thanks in advance for your help.

I"m stationed in Korea, and this works for me:

<?php

$us_offset = -5;//GM time to US Central Time
$kr_offset = 9;//GM time to Korean Time

$gm_hour = gmstrftime ("%H", time());//Find GM Hour
echo "GM Hour = $gm_hour<BR>\n";
echo "Korean Time = " . strftime("%H:%M:%S",mktime($gm_hour+$kr_offset, date("i"), date("s"), date("d"), date("m"), date("Y"))) . "<BR>\n";
echo "US Central Time = " . strftime("%H:%M:%S",mktime($gm_hour+$us_offset, date("i"), date("s"), date("d"), date("m"), date("Y"))) . "<BR>\n";

?>

OUTPUT:
GM Hour = 10
Korean Time = 19:25:30
US Central Time = 05:25:30

Your solution is guaranteed to break if it's called right at midnight
and the various calls to date() happen to straddle that magic moment.
But all you have to do to fix it is to capture the current time
once and for all with time() and then use that result as the
second argument to date().
