get UTC time in PHP

Question

How can I get UTC/GMT +/- time stamp using PHP's date() function? For example, if I try

date("Y-m-d H:i:s", time());  

I will get Unix time stamp; but I need to get UTC/GMT time stamp with string GMT/UTC+/-0400 or GMT/UTC+/-1000 based on local timings.

Answer 1

Using gmdate will always return a GMT date. Syntax is same as for date.

Answer 2

A simple gmdate() will suffice

<?php print gmdate("Y-m-d\TH:i:s\Z");
