Overview

The sleepuntil program will sleep up to a specified time and then either exit or else perform some specified action. The time to sleep until can either be given explicitly or else can be given in terms of a regular interval. If a regular interval is given then the first wait will be until the first instance of that interval. For instance, if you have specified that the program should wake up every hour on the hour and it is five minutes to the hour when you run the program then the first sleep will only be for 5 minutes not for an hour.
