[Tue Jan 14 11:57:29 2014] [error] [client 91.105.184.157] PHP Warning: date() [function.date]: 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 'UTC' for 'UTC/0.0/no DST' instead in www/install/index.php on line 584, referer: /install/

Как решить?
