Question

How can i convert a date like this: 2012-07-16 01:00:00 +00 (it's in the UTC +00:00 timezone) to UTC +04:00 timezone? Ensuring that daylight saving will be handelled correctly?

Answer 1

Use DateTime and DateTimeZone.

$date = new DateTime('2012-07-16 01:00:00 +00');
$date->setTimezone(new DateTimeZone('Europe/Moscow')); // +04

echo $date->format('Y-m-d H:i:s'); // 2012-07-15 05:00:00
