Quadra 950: System clock <--> Hardware clock questions

[Hank <compdata@portsys.net>]

Hi!

Finally got the Quadra 950 working without having to manually reboot the 
machine.
I've asked a few questions about this before--thanks for the tips. But 
now the info has
finally sunk in and I found out where the bugs are in the startup and 
shutdown sequence
and just elimated them from occuring: i.e. the scripts calling for a 
hwclock --systohc.

I guess have a couple of questions? How does the system clock keep time 
if it does not
use the hardware clock?

What exactly is the problem with the 900 series?  Why can't the system 
clock copy itself
to the hardware clock during shutdown and reboot?

Just curious,

Hank
