I think it did step and more than once. I'd suspect a bug in the
firmware in the GPS-UTC offset handling, current offset is 15 seconds
and that is visible in one of the ntpq outputs in the original post.

Would be interesting to know if this happens on every ntpd restart or
only shortly after the GPS unit was powered up.
