Please note that granularity > does not mean accuracy (it has never been). Right. For example, all resoloution better than a second is arrived at through interpolation, and has been for a long time. SunOS 4 interpolated to a resoloution of 4uS (based on the time it took to make a system call vs. the speed of the hardware at the time).
