Key Points Repeatability is the measurement of variation when a process is done multiple times. Precision is the means of ...

In fact, accuracy is a measure of closeness while precision is a measure of reproducibility. That means that you can be accurate but not precise, or precise but no accurate. Or both, if you’re ...

The Difference Between Accuracy and Precision Jan. 5, 2016 I have a low tolerance for precise inaccuracy, though I’ve been in such situations more often than I care to admit.

Apart from that “arduino” “exact time” and if you know what precision and accuracy is, you should also know that “exact time” is only a theoretical concept. I’ll quit now befor.
