Yes. I already knew about ntpd over ntpdate. It's was just that since
getting the new hardware I had noticed a sudden loss of time so wanted
to see how much was being lost (and thought is was just the motherboard
clock out until it occurred again)
I already used ntpd.

Hmm, I forgot that each machine will have different drift factors and
stuff. Cleared /etc/adjtime and /var/lib/ntp/ntp.drift so will see how
it goes now. (I also added better time servers)

Thanks
