If you want everyone on your system to have their KSH time out after, say,
5 minutes, set TMOUT in the /etc/profile to 5*60 seconds or 300.  This
would be the line you'd add to /etc/profile:

TMOUT=300; export  TMOUT; readonly TMOUT

With the readonly on there, the users cannot change or unset it in their
login shell.
