Sorry, I should have made this more clear.  I was assuming that timer 1 was
being used with a CCP module to create periodic interrupts at your period of
choice.  Or, the same trick can be used with timer 2 which can be used with
its period register.  In either case there will be no long term timing
creep, just jitter due to unpredictable interrupt latency.
