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"));

Why do you subtract exactly 5 hours?
The 5 hours are just an example, for example if your server is on a country with a 5 hour time difference with the country you are in.
