Depends on which crontab you are using.

There is a system wide crontab in /etc/crontab (as well as files in the 
/etc/cron.d directory).  They require you to specify the user to run as 
(ie,, with the root.)

However, each user is also allowed to have his/her own crontab file 
(kept in the /var/spool/cron/crontabs directory).  These are the cron 
files that get intalled with the crontab command, and you do not specify 
a username in the file for them)
