In the .logout file add this line
-----------------------------------
echo logout time `date`>> .daylogs/masterlog
This script assumes you have a hidden
directory called .daylogs this helps keep it
out of sight and away from prying eyes and
if you keep root ownership of the directory
change the mode to:
chmod 744 .daylogs
This will not allow anyone to get in to the
directory to look around.
