The only way I can think of doing it off the top of my head would be to modify
both programs to look at the real-time clock, then quit and fire up the other
program at the appointed hour.  A simple modification if the programs were
written in-house, but probably quite complex if you're talking about pre-
packaged programs.

Maybe it would be possible to make the clock generate interrupts periodically.
A constantly-resident interrupt handler could then check the time of day and
run the other program if appropriate.  If not, it would simply return to the
first.
