TimeTrex Time and Attendance

how often should you run the cron.php I thinking I'm doing it to often right now I wanted to see what is the recommended time between running cron.php

The more often it runs the better, as 99% of the time nothing happens, but if you don't run it every minute than some maintenance jobs may be skipped and won't run when they should.

yea I'm running it every minute as it stands right now just wasn't sure if that was correct.
