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/Paris' for '2.0/DST' instead in C:\urs\server\httpd\ezp\lib\ezutils\classes\ezdebug.php on line 879

Informacja: Since PHP 5.1.0 (when the date/time functions were rewritten), every call to a date/time function will generate a E_NOTICE if the timezone isn't valid, and/or a E_STRICT message if using the system settings or the TZ environment variable.

Jako że to nie jest Twój skrypt, zamiast jego poprawy chyba lepsze będzie...
