Type: [2048] date() [function.date]: 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/Berlin' for 'CET/1.0/no DST' instead, line 154 of file /usr/local/apache/www/htdocs/artel-elektro.pl/classes/vMain.php

RTFM!
