local to gmt function doesn't work

More than one way to skin a cat:

PHP Code:

<?php
$date = new DateTime('now', new DateTimeZone('Europe/Berlin'));

$tz = $date->getTimezone();

echo $date->format('Y-m-d H:i:s') . " in " . $tz->getName() . "<br />";

$date->setTimezone(new DateTimeZone('Asia/Singapore'));

$tz = $date->getTimezone();

echo $date->format('Y-m-d H:i:s') . " in " . $tz->getName() . "<br />";

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

$tz = $date->getTimezone();

echo $date->format('Y-m-d H:i:s') . " in " . $tz->getName() . "<br />";

$date->setTimezone(new DateTimeZone('America/Los_Angeles'));

$tz = $date->getTimezone();

echo $date->format('Y-m-d H:i:s') . " in " . $tz->getName() . "<br />";

Why can't use the Time_Referenece only to change the timezone?

I don't know, but I never use it. I always use PHP native classes and functions when they do what I need. Maybe somebody else will give you an answer, but my code works ...
