System.currentTimeMillis vs System.nanoTime

Question

Accuracy Vs. Precision

What I would like to know is whether I should use System.currentTimeMillis() or System.nanoTime()<

Answer 1

one thing here is the inconsistency of the nanoTime method.it does not give very consistent values for the same input.currentTimeMillis does much better in terms of performance and consistency,and also ,though not as precise as nanoTime,has a lower margin of error,and therefore more accuracy in its value. i would therefore suggest that you use currentTimeMillis
