Why is my System.nanoTime() broken?

Question

Myself and another developer on my time recently moved from a Core 2 Duo machine at work to a new Core 2 Quad 9505; both running Windows XP SP3 32-bit with JDK 1.6.0_18.

Answer 1

On my system (Windows 7 64-Bit, Core i7 980X):

nanosTaken=4999902563
millisTaken=5001

System.nanoTime() uses OS-specific calls, so I expect that you are seeing a bug in your Windows/processor combination.
