> :
> System.nanoTime(), which is guaranteed to be monotonic, is now used to
> recored elapsed times. In several places, conversion from nano seconds to
> some target unit (e.g. seconds, milli seconds) is performed using hard-coded
> conversion constants, which is prone to mistakes.
> It would be nice to use {{TimeUnit.TARGETUNIT.convert(sourceDuration,
> TimeUnit.SOURCEUNIT)}} instead.
