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.

In my setup setTimezone() does modify the date, as well as the TZ. 





Code:





<?php


$dt_obj = new DateTime('2009-06-25 12:00:00');


echo $dt_obj->format(DATE_RFC822) . "\n";


$dt_obj->setTimezone(new DateTimeZone('GMT'));


echo $dt_obj->format(DATE_RFC822);


?>





Output:


Thu, 25 Jun 09 12:00:00 -0400


Thu, 25 Jun 09 16:00:00 +0000

Btw: setTimezone() does NOT modify the date, just the TZ. I tested this just to make sure 'cause the documentation doesn't tell.
