What do I need to set up in order to have the same results on any server?
Thanks

I am sure is a matter of time zone, but I do not know how to be aware of this.

Answer 1

use gmdate to return gmt time

function fDate($what){echo gmdate('D Y-m-d',$what).'<br>';}

see if you still have issues.

Answer 2

Set the default timezone

Set it to UTC or GMT and you can use it as a basis for all your servers

date_default_timezone_set('UTC'); 

fdate(time());  // will return the UTC time

Answer 3

Include date_default_timezone_set at the beginning of your script based on your desired timezone.

<?php
date_default_timezone_set('America/Los_Angeles');
?>
