I think you are off by a few orders of magnitude.  A million ns is a ms.  
It's easy to get NTP running much than that.

I agree that most systems running NTP are unlikely to notice the sawtooth 
correction, but this is time-nuts.

Have the PTP guys gotten good enough to notice hanging bridges yet?  (as the 
phase of their clocks  drifts)
