That's pretty much what I was planning on doing, after I looked
up specs on the CPU oscillator vs. the Dallas RTC. If the
accuracies and tempcos are similar, there's no loss.  If the
RTC is a lot more accurate than the CPU clock, then using a FLL
or PLL algorithm to lock the system time and the RTC together
would be cool.
