Adjust Server Time In PHP
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. Adjust the server time to a different time zone for specific issues in time differences. 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.
$today = date('Y-m-d-G');
$today = strftime("%Y-%m-%d-%H", strtotime("$today -5 hour"));
