1.11.7.4 Changing the Expire Time of a Session

You can change the expire time of a session using manager.setExpire(). The method takes expireTime which is the time you want the session to expire in seconds since the epoch (00:00:00 UTC, January 1, 1970) This is the format returned by time.time(). expireTime is not the extra number of seconds to allow the session to exist for.
