You should not be tryng to use the session as a timer. There's Javascript mechanisms for that.

The way to store a system timestamp in a session is to create a Long object like this:
Long tstamp = new Long( System.currentTimeMillis() );
and store it in the session:
session.setAttribute("lastaction", tstamp);
(you have to use a Long because sessions only store object references)
On subsequent requests you can recover the timestamp value and compute the number of milliseconds in the interval.
