Stopwatch resistant against system time changes

I want to make a stopwatch in Java, which is immune against system time changes.

long start = System.nanoTime();

// System time changes

long stop = System.nanoTime();

long elapsed = start - stop;

So the problem with this code is that when the system time is changing, then the time measurement is wrong.

The above code should be resistant against system time changes according to the API:

This method can only be used to measure elapsed time and is not related to any other notion of system or wall-clock time.
