date_default_timezone_set() and cron job

Hi;

I have a cron job (called x.php) for one of my sites which is hosted on a hostgator server.

I have used date_default_timezone_set("Paris/Europe") in my x.php file.

When I call x.php from browser, It's OK but when cron job runs, it shows me date_default_timezone_set() function as a fault.

Any comment for this?

Regards

 

I guess that is a cron job call error. How do you run/call the cron job?
