Examples
Example #1 gmdate() example
When run in Finland (GMT +0200), the first line below prints "Jan 01
1998 00:00:00", while the second prints "Dec 31 1997 22:00:00".
<?php
echo date("M d Y H:i:s", mktime(0, 0, 0, 1, 1, 1998));
echo gmdate("M d Y H:i:s", mktime(0, 0, 0, 1, 1, 1998));

ATTN! The following code produces different result in PHP 7 and PHP 8!
gmdate('Y-m-d\TH:i:s', null);
In PHP 7 null in gmdate('Y-m-d\TH:i:s', null) translated as 0, although gmdate('Y-m-d\TH:i:s'); (w/o 2nd parameter specified) works as it should.
This issue is fixed in PHP 8.
