I didn't specifically test that. I just observed that it corrected the initial offset of around 1 sec in less than 10 minutes. I'll do more detailed tests tomorrow.
One thing I did notice. On macOS 10.12 the frequency on the machine I use seems to mostly hover in the range 16 to 19 ppm, depending on temperature, other workload etc.
On macOS 10.13, it seems to be more like 17.5 to 20.5 ppm, again depending on temperature, workload.
I was a little surprised to note the difference because it is the same hardware in both cases. Maybe I need to test that a little more to see if its a real or imaginary (on my part) difference.
