Changing Timezone

If you need your WHMCS system to operate in a different timezone to that which your server is configured with, you can do this by simply adding the line below to your WHMCS configuration.php file:

date_default_timezone_set('Europe/London'); 

This changes the timezone for the WHMCS installation to the locality you specify so you just need to replace the 'Europe/London' part with the location you are based in.

For a full list of the available timezone localities you can use, please refer to http://www.php.net/manual/en/timezones.php
