I suspect these terms mean what you choose them to mean.  Here is what 
Google has to offer:


(includes both "number of digits" and "degree of refinement")


(includes "measure of accuracy or dynamic range of an A/D or D/A 
converter" and "smallest quantity that can be measured").

>From this, I would suggest:

precision - degree of correctness

resolution - accuracy of measurement

Perhaps NTP has its own definitions?
