I hooked up a 32.768kHz crystal and the thing ran really well. There is the ability to make very fine adjustments to the clock accuracy too.
I'm currently using a 18F26K22 internal timer off a 32.768kHz crystal, when main power is disconnected the clock can run for very long periods from a supercap by only waking from low power sleep mode to service the 1 second interrupt and then sleeping again. I think one of the pics with RTC also has an onboard temperature sensor so adding a form of temperature sensing is easy too.
