Any idea what causes this? Hardware issues? 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.

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. - Mike </blockquote></div>
