I think it's important to mention with the DateTime class that if you're trying to create a system that should store UNIX timestamps in UTC/GMT, and then convert them to a desired custom time-zone when they need to be displayed, using the following code is a good idea:

<?php
date_default_timezone_set
('UTC');
?>

Even if you use something like:

<?php
$date
->setTimezone( new DateTimeZone('UTC') );
?>

... before you store the value, it doesn't seem to work because PHP is already trying to convert it to the default timezone.
