It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting 
or the date_default_timezone_set() function. In case you used any of those methods and you are still
 
getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/London' for '0.0/no DST' 
instead in C:\Apache2.2\htdocs\websites\test\process.php on line 6

date_default_timezone_set( 'Europe/London' ); // Or the timezone of your choice.
