Unidirectional drift and periodic clock steps are a good indicator that
the clock drift exceeds ntpd's correction capabilities. In these cases
adjusting the tick to bring the clock drift within +/- 500PPM is
sometimes the solution.
As suggested elsewhere in this thread stopping ntpd, deleting the
drift.file, and starting ntpd is another potential solution.
