No, Schedule::Cron is used to create a "cron-like" scheduler.  It doesn't make use of the actual cron daemon.

If you want to go through the normal cron mechanism, just create create the file you want to add to the crontab, and insert it with crontab <file>.

You can get more information about it from the man page for crontab:  man crontab.

Naturally, you can automate the process quite easily with Perl.
