Adjusting date() function for time zones

[Epsilon]

I'm writing a script for a guy who wants current Pacific date and time displayed, but his server in on the East coast. He's on a virtual hosting account so I can't adjust the time settings on the server.

I'm using

$this_date = date("D M j, Y, g:i A")

Which produces something like:
Fri Feb 27, 2004, 6:33 AM

Is there a way to adjust this for the 3 hour time difference or should I be using a different function? I thought about just using time(), then subtracting 10800 seconds from it and converting it into a formatted date like the one above, but I'm not sure how to do the conversion part.

Nevermind, I should have just tried it before I asked.

$p_time = time() - 10800;
$this_date = date("D M j, Y, g:i A",$p_time);

Works perfect.
