If your clock runs 3 minutes faster after 45 days, congratulations,
you are running at 1.000046296 times your Mac II's rated speed, and
probably have the fastest machine on your block, so I'm envious 8-).

I haven't noticed my Mac II's clock running fast, but I use a PD
utility called "Setclock" to dial up a time standard and reset my
clock.  Furthermore, if it is your clock crystal that's oscillating a
little bit fast, then you could try replacing it, however, I suspect
the time warp occurs when your machine is turned off and the data is
in PRAM.  Perhaps the PRAM clock is calibrated differently (due to its
low-power nature), and can recalibrated?
