One application of having two independant clocks in your situation could be to
have the mains frequency attached to TIMER0/1, which is more accurate than a
regular crystal. Since you can't run the actual PIC off this frequency, you
still need your regular xtal... but that's what I have done for my clock, used
the mains frequency to drive the TIMER0. Seems to be more accurate...
