This isn't really a Perl question. It's also OS dependent. If you are on a unixish platform, you should read crontab(5). I can't help you if you are on Windows, but I'm sure someone else can.

cygwin has a good windows port of cron.

on windows the AT-command can be used.

The basics of scheduling are as such:

1. Define a schedule and put it into some storage mechanism. (RDBMS's are usually used for this.)
2. A process every so often (usually, every second or minute) checks this storage mechanism and launches every action that should be taken at the time of checking.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.

for windows servers you may be able to do it w/ a scheduled task, but I don't know if it runs like a cronjob.

Scheduled tasks in the Windows environment will do this, but I personally have found them a touch flakey to get set up. But once you get used to some of the syntax in question, they are pretty straightforward. I prefer crontab, but both are better than using the batch queue under OpenVMS :-)
