Thema: Warning: strtotime() [function.strtotime]

Hallo,

was kann ich gegen folgende Fehlermeldung machen ?:

Warning: strtotime() [function.strtotime]: 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/web620/html/hvl/libraries/joomla/utilities/date.php on line 56
