If that is the case you are probably better off using the reference
implementation of ntp which disciplines your clock on an ongoing basis
by adjusting the frequency of the clock and not just sets the time. I
can't tell for sure but I believe that Tardis just sets the time and
does not adjust the clock frequency in order for it to remain in synch.
I remember contacting Chris over 10 years ago about Tardis but it was
not about that kind of detail.
