The OS' clock resolution is in play here, which depending on your OS will
give you varying results. Also, on Java 9, you get better clock resolution

Hi,
I am tad confused about the StopWatch resolution. I have a very basic JUnit
test that starts a stopwatch, wait for 10ms and then stops it, and checks the
value. In about 40% of the cases it is less than the 10ms wait time.
Is that expected? What is my blind spot?
Regards,
Erwin
