title: How to use session.getLastAccessedTime()?
body: <p>I've to use a mechanism to track the last user logout (or when his session expired), can I do this?</p>
  
  <p>I've read about this method <code>session.getLastAccessedTime();</code> but I don't understand how it works. So, there are methods to get timestamp when user was disconnected from my web page (Logout or Timeout)?</p>
