Examples

Example #1 Setting and getting DateTimeZone objects


<?php
date_default_timezone_set('Europe/London');

$datetime = new DateTime('2008-08-03 12:35:23');
echo $datetime->getTimezone()->getName() . "\n";

$datetime = new DateTime('2008-08-03 12:35:23');
$la_time = new DateTimeZone('America/Los_Angeles');
$datetime->setTimezone($la_time);
echo $datetime->getTimezone()->getName();
?>

The above example will output:

Europe/London
America/Los_Angeles


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.

add a note

DateTime::sub

DateTime::setTimestamp
