Again, I don't think that will be effected.  I've had a hardware clock, either 
in the b&B interface, a Disto 4n1, or now in the TC^3 scsi interface, never 
had a problem with any of them that fiddling around with the driver didn't 
fix.  The most obvious one was the clock driver Tony D. supplied with his 
4n1, it ran perfect time when powered down, but lost about 6 minutes an hour 
powered up.  That turned out to be that Tony was using the wrong freeze 
command while the clock was being read, he was stopping the whole clock, when 
what he really wanted to do was freeze the ripple counters long enough to get 
a good reading.  Once that was fixed, even the 4n1 kept excellent time.
