to get the GMT date, you just have to use gmdate, this automaticly converts the local time to gmt.

to convert it back to singapore time, use the mktime() function: you enter the hours, minutes and seconds and it will create a new time. for you this could look like this:

PHP Code:

$gmt = gmdate("H:i");

$singapore_time = date("H:i", mktime(gmdate("H")+5, gmdate("i")+30, gmdate("s"), gmdate("m"), gmdate("d"), gmdate("Y"))); 

maybe there's a simpeler sollution, but this is one i just found, while looking on www.php.net,
