Method Detail

getTimeNS

public static long getTimeNS()

Gets the current time of this thread in nanoseconds from the most accurate timer available on the system. The returned value will be the current time in nanoseconds precision but not necessarily nanoseconds accuracy.

The intended use case of this method is to measure the time a certain action takes by making successive calls to it. It should not be used to measure total times in the sense of a time stamp.

Returns:

the current thread's time in nanoseconds
