description:
pull up rev 1.50 from trunk (requested by sommerfeld):
  If using kernel NTP PLL, initialize "fixtick" to a reasonable
  approximation of reality if machine-dependent code doesn't.  This
  allows a NetBSD/alpha kernel (where hz=1024) with "options NTP" to
  synch up quite nicely (as opposed to having an frequency error of
  ~560ppm, which is outside the capture range of the PLL).
