Key words for clocks and clock measurement include:
precision, accuracy, stability, resolution, and granularity.
Here's an informal stab at definitions for you:
Accuracy is how close a clock is to an accepted standard.
Precision relates to how consistent measurements are.
Stability refers to how well a clock keeps time over time.
Resolution is how precise one can measure.
Granularity is the minimum [digital] increment of one reading to another.
