Note that the magnitude of the correction is decreasing each time, so
your clock is being corrected -- just rather slowly. What I expect
happened is that your clock was way off at boot and you didn't force a
one-time complete correction (one of the options to ntpd). Except when
an initial complete correction is forced, ntpd only makes small
adjustments to the clock rate, so it's expected that a large error will
take a long time to correct completely.
