I don't believe this will be an issue; my understanding of ntpd is
that it well understands this sort of issue, and rather than cause the
system time to jump back it will slow the clock down for a while until
it is accurate.

I agree with Greg.  A word of caution.  I believe that he is relying
on you using ntpd to make the initial correction in the time, as well
as
to protect you from future drift.  Check in ntpd's manual.
