Cool!  I have used that approach, but not for specific times and for 
much shorter times.

I think the way to do what you're asking is to "convert" the date/time 
you need to seconds and subtract the current seconds.  Send in that 
many seconds.  You can make a general handler to do that.

However, the every-minute poll looking at the time will not take that 
much overhead and might have some advantages.  It might be able to 
handle the computer rebooting or the computer left on overnight.  There 
might be other ways in which it is more robust, such as when the time 
gets corrected.
