I have a server that has a time drift of around a minute every hour.
Overnight, that is pretty extreme and as this is a PVR, it causes problems.
I have NTP enabled but am still getting this drift and NTP is not
correcting or putting much in the logs ( no exit messages )
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.
