ur requirement is very unclear.
do you want to log the login and logout for every user ? you can do that by printing the date in the /etc/profile file.

set watch = (1 any any)

will report any login or logout every one minute on interactive shells, or the builtin 'log' if you don't want to wait.

If you want to log the activity the system login and logout files files are where to put your commnds, see 'man tcsh'
