If you don't always store the session (Apache::Session doesn't store unless you modify data in the session) then you have to update the timestamp on load to be accurate. If you want to be frugal, you might make the store operation update the timestamp, and then install a cleanup handler that will update the timestamp only if the session was not stored. - Perrin
