Example

Example of both strftime() and gmstrftime():

<?php
echo(strftime("%b %d %Y %X", mktime(20,0,0,12,31,98))."<br />");
echo(gmstrftime("%b %d %Y %X", mktime(20,0,0,12,31,98))."<br />");
//Print the current date, time, and time zone.
echo(gmstrftime("It is %a on %b %d, %Y, %X time zone: %Z",time()));
?>

The output of the code above could be:

Dec 31 1998 20:00:00
Dec 31 1998 19:00:00
It is Wed on Jan 25, 2006, 11:32:10 time zone: W. Europe Standard Time
