No, and nor would it be a sensible thing to do. NTP will not step until
both a sanity check timer (default 15 minutes) has expired and enough
sample intervals have passed to get four or five samples consistent with
the new time.

Nor would ntpd be, if it behaved like this. I should, however, point
out that w32time is far from NTP compliant unless you change most of its
registry settings, and even if the software clock has good time on
Windows, there will still be quite a bit of jitter in timing of real
world events by applications. In any case, Windows is a poor platform
for timing critical applications.
