Where does the 10195 number come from?
I just like to understand what the issue cause is and what the command actually does.
Thank you for the assistance.

I had the same problem on a brand-new DC7700. ntp can only correct
within 500 ppm (0.05%). For some reason, the DC700 clock was 1.95% too fast!
To fix this, I added this to /etc/rc.local:
/sbin/adjtimex --tick=10195
This adjusts the "tick rate" at every boot-up. Once the basic accuracy
is corrected by this, ntp can fine-tune it exactly.
