I recently changed my error settings in php.ini from E_ALL to E_ALL | E_STRICT.
Now at the top of my pages i'm getting a warning message...
Strict Standards: strftime() [function.strftime]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable 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.
I presume I need to change a timezone setting in php.ini, but i've no idea which.
Help.
