Convert Unix Timestamp to time zone?

Use DateTime and DateTimeZone:

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

As because edit queue for John Conde's answer is full I'll add more detailed answer.

From DateTime::__construct(string $time, DateTimeZone $timezone)

The $timezone parameter and the current timezone are ignored when the $time parameter either is a UNIX timestamp (e.g. @946684800)…

This is the main reason why you should always specify timezone, even default, when creating DateTime objects from unix timestamp. See explained code inspired by John Conde's answer:

$dt = new DateTime('@1369490592');// use your default timezone to work correctly with unix timestamps// and in line with other parts of your applicationdate_default_timezone_set ('America/Chicago'); // somewhere on bootstrapping time…$dt->setTimeZone(new DateTimeZone(date_default_timezone_get()));// set timezone to convert time to the other timezone$dt->setTimeZone(new DateTimeZone('America/Chicago'));echo $dt->format('F j, Y, g:i a');

An easier way to do that is:

While using gmdate(), add your time zone in seconds to unix_stamp in gmdate.

Consider my time zone is GMT+5:30. So 5 hr 30 min in seconds will be 19800

So, I'll do this:

gmdate("F j, Y, g:i a", 1369490592+19800)
