java - Stopwatch resistant against system time changes -

-

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

  Long start = System.nanoTime (); // System time stops longer = System.nanoTime (); Long time = start - stop;

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

< Blockquote>

This method can only be used for time elapsed and is related to any other notion of system or wall clock.
