in reply to Script to poll every hour

This sounds more like something that should be solved via a cron job, particularly since it sounds like something that should be persistent. The Windows equivalent is using the scheduler, which is found via
Start > Programs > Accessories > System Tools > Task Scheduler
or something like that, depending on your version.

That is, of course, not the question you asked.

To run a script and then pause it until 20 past the hour, you should use localtime to get the minutes (my $min = (localtime)[1];) and then sleep 60 * the mod of the difference between that and the target (sleep(60 * ((20 - $min) % 60))). If you need better precision, you can include seconds (or even milliseconds) in that calculation.

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.
