How Long a process runs for ?

[Rick]

There a app, I used in the Terminal window, I know it does take a few hours to 
run, however... I would like to know exactly how long so I could setup a cron 
job.

Is there a way to find out how long a application ran for ?

I've check a bunch of log files, and could not find the application. to see 
when it started and when it stop.

also it would be nice, if my terminal window would display the current date 
and time in the window before the flashing cursor.


TIA -
Richard
