TYPO3 Core

The page module shows a lot of PHP warnings for mktime in PHP 5.3.1.

PHP Warning
PHP Warning: mktime() [function.mktime]: 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/Berlin' for 'CET/1.0/no DST' instead in /var/www/html/typo3conf/temp_CACHED_ps006c_ext_tables.php line 155
