IPS Driver Error

IPB WARNING [2] mysql_query() [function.mysql-query]: Unable to save result set (Line: 457 of /ips_kernel/class_db_mysql.php)
IPB WARNING [2] 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 'Europe/Moscow' for 'MSD/4.0/DST' instead (Line: 692 of /ips_kernel/class_db.php)
