I found unexpected behaviour when passing a timestamp.

timezone seems to always be GMT+0000 unless setTimezone() is set.



<?php



$MNTTZ = new DateTimeZone('America/Denver');

$ts = 1336476757;



$dt = new DateTime("@$ts", $MNTTZ);

var_dump($dt->format('T'), $dt->format('U'));



$dt->setTimezone($MNTTZ);

var_dump($dt->format('T'), $dt->format('U'));



/** Output:

string(8) "GMT+0000"

string(10) "1336476757"

string(3) "MDT"

string(10) "1336476757"

**/



?>

The timestamp value represented by the DateTime object is not modified when you set the timezone using this method.  Only the timezone, and thus the resulting display formatting, is affected.



This can be seen using the following test code:

<?php

$MNTTZ = new DateTimeZone('America/Denver');

$ESTTZ = new DateTimeZone('America/New_York');



$dt = new DateTime('11/24/2009 2:00 pm', $MNTTZ);

var_dump($dt->format(DATE_RFC822), $dt->format('U'));

$dt->setTimezone($ESTTZ);

var_dump($dt->format(DATE_RFC822), $dt->format('U'));



/** Output:

string(29) "Tue, 24 Nov 09 14:00:00 -0700"

string(10) "1259096400"

string(29) "Tue, 24 Nov 09 16:00:00 -0500"

string(10) "1259096400"

**/

?>



As such, you can use this to easily convert between timezones for display purposes.
