Resolution, Precision, Accuracy

Because the electronic timer can divide time into smaller units than the other clocks, it can get closer to the true value of the measure.

The smallest change in quantity or size that a measurement system can detect is called its resolution.

While electronic timers have a very high resolution, there are measuring devices with even higher resolution.

The uncertainty of the NIST-F1 atomic clock is less than 1 x 10-15, which means it would neither gain nor lose a second in more than 30 million years!
