Description:
------------
The function gmdate() actually returns UTC time instead of GMT and it's different on summer time (GMT = UTC+1 hour). Learn more here:
http://en.wikipedia.org/wiki/GMT
http://en.wikipedia.org/wiki/UTC

For example, now I'm situated in Kiev, Ukraine (GMT+2), it's summer time and it's 04:00AM here, but in London (in GMT zone) it's 02:00AM, however the function returns 01:00AM - it's not GMT, it's UTC time. This function should work well in winter.

Reproduce code:
---------------
<?php
	echo gmdate('H:i', time());
?>

Expected result:
----------------
02:00AM



Actual result:
--------------
01:00AM

@rosty.kerei: There's a fundamental error in your original report, as GMT is never UTC+1: GMT effectively *is* UTC.  Here in the UK right now, we're on British Summer Time (BST, UTC+1, GMT+1), so London, although in a "GMT zone", is not currently on GMT. In the autumn, we will shift back an hour and London will then indeed be on GMT.
