Erik,
If you want to experiment with trimming the oscillator for the clock,
you can try varying the capacitance of C7 and C8 on the KXBC3 option board.
Nominal capacitor values are +/- 5%, so you may be able to find suitable
capacitors that vary a bit from the nominal 15pF value that will set
your RTC "right on". A few pF either side will likely make a
significant difference.
Again, a bit of experimentation will be in order to get it exactly
correct. The actual capacitor value can vary from the nominal value by
0.75pF and still be in-spec, so only add/subtract a bit at a time.
Monitoring the results over a long time period can be tedious work, but
if you want it "spot on", it may be worth the effort for you.
