So when a user logs in you write a user_id and datestamp to a field in your sessions table. Every time the person accesses a page you update the datestamp in that record. Then you run a function that checks every X minutes if the timestamp is older than X minutes and if so you log the person out? Is this correct? How exactly do you log them out? By issuing a command to clear the session variables saved during login, thus causing function on each page that checks for valid login to fail?
