After updating to latest git:

# ntpq -c kerninfo
associd=0 status=0415 leap_none, sync_uhf_radio, 1 event, clock_sync,
pll offset:            96.4811
pll frequency:         500
maximum error:         0.121677
estimated error:       2.2e-05
kernel status:         pll nano
pll time constant:     6
precision:             1e-06
frequency tolerance:   500
pps frequency:         0
pps stability:         0
pps jitter:            0
calibration interval   0
calibration cycles:    0
jitter exceeded:       0
stability exceeded:    0
calibration errors:    0

How to proceed to normalize the offset?
