There's a couple of different versions of cron available, and you don't specify which one you use, so I'll just answer with what I'm most familiar with.
Dillon's cron (the cron used in Slackware - crond) says this in it's man page: "Whenever crond must run a job, it first creates a daemon-owned temporary file O_EXCL and O_APPEND to store any output, then fork()s and changes its user and group permissions to match that of the user the job is being run for, then exec's /bin/sh -c to run the job." So if you have crond, just run 'crontab -e [user]' to create [user]'s crontab, and it will be run with [user]'s uid & gid. In my quick skim of vixie cron's man pages (vixie cron is another common cron) I didn't see anything one way or another about what uid it runs as, and I've never used it myself, so if you use vixie cron I don't know what uid the job will run as. But I do know it does have a crontab for each user, so I would guess it would run as the user who owns the crontab. HTH, Conway S.
