I found notes in includes/session.php

PHP Code:

 // if this line is removed (say to be replaced by a cron job, you will need to change all of the
'online'
                        // status indicators as they use $userinfo['lastactivity'] to determine if a user is online which
relies
                        // on this to be updated in real time.
                        $DB_site->shutdown_query("
                                UPDATE " . TABLE_PREFIX . "user
                                SET lastactivity = " . TIMENOW . "
                                WHERE userid = $bbuserinfo[userid]
                        ", 'lastvisit'); 


Maybe cron job code already exists, but where it is ?
