crontab: Are my Cron Jobs Running Fine?

How can I tell if my cronjobs are running ok since they don't produce any output?
Check the following file:

 /var/cron/log   : (cron history information)
 /var/cron/olog : (moves log file to /var/cron/olog if log file exceeds system ulimit)









 The file looks something like this: 

 ! *** cron started *** pid = 260 Tue Jun 4 00:30:56 2002
 >  CMD: [ -x /usr/sbin/rtc ] && /usr/sbin/rtc -c > /dev/null 2>&1
 >  root 429 c Tue Jun  4 02:01:00 2002
 <  root 429 c Tue Jun  4 02:01:00 2002 rc=1
 >  CMD: /usr/sbin/logadm
 >  root 440 c Tue Jun  4 03:10:00 2002
 <  root 440 c Tue Jun  4 03:10:00 2002
 >  CMD: [ -x /usr/lib/gss/gsscred_clean ] && /usr/lib/gss/gsscred_clean
 >  root 452 c Tue Jun  4 03:30:00 2002
 <  root 452 c Tue Jun  4 03:30:00 2002

It provided the following:

• The CMD is the command that was run
• Next entry is the time the job started
• Next is the time the job finished
• The rc is the return code from the job
