Adjust Server Time

Sometimes the time set on your server isn't accurate to what your local time is. If you can't change it, you can adjust it yourself.

$today = date('Y-m-d-G');
$today = strftime("%Y-%m-%d-%H", strtotime("$today -5 hour"));

If your server thought it was 12 midnight, but it was really 7 pm, this will roll the $today variable back five hours to be correct.

    The preferred way for PHP5 and above is to use:


    A list of the possible values are here:

  2. Yep, definitely use date_default_timezone_set(‘mytimezone’);

    Yes i also support to use date_default_timezone_set(‘Your Time Zone’);
    If you have full control over your server then you can change php.ini to locate your timezone.
