That's almost certainly totally the wrong thing to do. If you have
short periods of increased interrupt latency or network latency, you
want a long poll interval so that the samples with the high offsets (and
delays) are ignored.
Forcing a short interval will make ntpd track the temporary errors in
the time measurements.
Offset is not a direct measure of the timekeeping error.
