I don't know what is wrong with the clock on the Q950. Mine uses ntp.
Are
you sure it works with 2.2?
I'm very sure that we never had a working RTC on the Q900/Q950. In
fact,
I believe that trying it crashed the system in 2.2. The kernel tried to
use one of the existing RTC routines on that hardware when it wasn't
the right thing to do. In particular it used the VIA bit-poking method
that really old macs need and that wasn't a good thing.
The caboose chip handles the RTC on these systems (and a few other
things as well) and we just simply don't know how to use it.
I don't know "how", but with 2.2 kernels I always had a correct date at
boot without any tricks. It is true though that with high CPU load we
had clockskew and that we didn't save back the date and hourtime to the
clock, thus any clock setting needed to be done from the mac side. A
compromoise, but better than the current situation.
Of course, in a perfect world, you could use EMILE and not install
macos at all (also saving space on those old SCSI disks) and
consequently everything needs to be supported inside linux.
