Let ntpd do what it does. If you are having trouble with your system
being within 10ms, find out why, do not try to bugger up ntpd. ntpd will
take a while (hours) to settle down but after that it should certainly
track better than 10ms. Some possibilities if not-- you are using
carrier pidgeons rather than ethernet to exchange packets (or your
ethernet is seriously deficient). 
You are trying to keep virtual machines on time
You are using Windows.
