I *was* aware of that, but that doesn't change the fact that ordinary 
applications only see the time updating on a tick; only ntpd benefits 
from the interpolation.  On modern Unices, all applications get high 
resolution clock readings.

Also, I believe that the zero point of the interpolation is rather 
sensitive to scheduling delays on loaded systems.
