A simple class that can be used to return an approximation of the elapsed time in nanoseconds in a human-readable format.
It also converts time periods between nanoseconds, hours, minutes, seconds, milliseconds, and microseconds.
import timeutils.Time;
long startTime = System.nanoTime();
...
long endTime = System.nanoTime();
// Create a Time instance
System.out.println(new Time(endTime - startTime));
// Do not create a Time instance, use the static method instead
System.out.println(Time.toString(endTime - startTime));| Period | Format | Approx. Percent Error |
