Convert Unix Timestamp to time zone?

Question

I have a unix timestamp that is set to +5, but I'd like to convert it to -5, EST Standard time. I would just make the time stamp be generated in that time zone, but I'm grabbing it from another source which is putting it at +5.

Current Unmodified Timestamp Being Converted Into A Date

<? echo gmdate("F j, Y, g:i a", 1369490592) ?>

Answer 1

Use DateTime and DateTimeZone:

$dt = new DateTime('@1369490592');
$dt->setTimeZone(new DateTimeZone('America/Chicago'));
echo $dt->format('F j, Y, g:i a');
