That's just one of the problems. It must be this one:

(from 108528-12)
4467264 GET_NATIVE_TIME for hummingbird/UIIe can return erroneous values

then there was the clock speed problem:

(from 108528-13)
4460876 Hummingbird (UIIe) system clocks consistently run fast

looks like the troubles are not yet over. I saw occasional glitches in the 
order of 2 or 32 seconds a couple of times per month (fewer in recent times), 
but 100 years?
