Release : 16.0
Component : CA Top Secret for z/OS
With LOCKTIME=020 and LTLOGOFF=YES, after 20 minutes of terminal inactivity, the terminal is locked and a user will have to re-enter their password to resume their terminal session.
If the user doesnt have activity after another 20 minutes, the user will be forced logged off because LTLOGOFF=YES.
So its a total of 40 minutes of inactivity will the user actually get logged off if there is no terminal activity by the user.
