Need a cron job need some output?No, but if there is output, it will be emailed to your login account (at least every version of cron on UNIX(ish) systems I've come across does).
Have a cron job a timeout?No, but you should be wary of multiple instances of scripts running because cron ran your script again when the last one hadn't finished.
To prevent that, you can employ a semaphore or something similar to alert other invocations of your script to the fact there's already a copy running.
