Is the clock at 10.0.0.5 good?
If all your adjustments are in the same direction, then your system
is probably broken. If they alternate signs, then something in your
network or remote clocks is probably confused.
One thing to try. What's in your drift file? (It's probably in
/var/lib/ntp/drift or /etc/ntp/drift ...) If that it a big number
like 500, try stopping ntpd, deleting that file, and restarting ntpd.
These are my opinions, not necessarily my employer's. I hate spam.
