What about:
@daily sleep ${RANDOM:0:2}m ; /some/cron/job.sh
Which gives you a jitter of up to 99 minutes.
Cheers,

60 is way more than we have on our jailers. Daily / security scripts are very
disk IO intensive so we end up with changing time in /etc/crontab in each jail
for periodic tasks.
The best way is to randomize these times on jail creation time.
