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.
