Hello,
The date and time used in the script will follow the server date time. You can adjust the date and time according to your requirements by updating the timezone setting on your server.
If you are using shared hosting, you can try to override it by setting the date and time from the config file.
date_default_timezone_set("_your_timezone_");
For your information, we will consider adding this option in the future version of the script to make it handy if the server time do not the same as local time.
Regards,
