I have a script that I'd like to run every two hours on the half-hour (i.e. at 3:30, 5:30, etc.). Doing this with NT's AT scheduler (and Unix's crontab, I think) would require 12 separate scheduling lines. That's not fun to administer if the schedule changes. I suppose I could find a more robust scheduler, but I'm curious if there's a Perlish solution my fellow monks like to employ in situations like this.

I started working on a simple sub to include in my script, which would sleep for a while, check the time, then come to life and run the main part of the script. I could fudge by with that in this case, but the script won't really start "on time", and this solution is not all that elegant.

What I'm imagining is some bit of code that wakes the script up at the right time, each time. I haven't tried a loop of code that continually checks the time without sleeping, because that seems like it would be extremely processor-intensive. I suppose this is exactly what schedulers are for, but is there a different/better solution?

Thanks!
