tcsh has the feature of printing time automatically after each command
executed (time variable). it also has 'precmd' and 'postcmd' aliases that
are executed (if set) before and after any command executed.
However tcsh is not bourne shell compatible, you'd have to learn working
with it (well, I prefer tcsh over bash)
