Will allow you to change the "Expire" time of "admin" and "customer" sessions. It changes both simultaneously.
It does this by altering the db.php file.
There is a write function within that file that updates the oc_session table "Expire" entry each time there is a user interaction in any panel.
This mod allows an easy way to set whatever time you would like for sessions to be timed out.
I patterned the xml off Navid Raeisi's code for his "admin manager sort" extension.
