ntpd -x ?
[from man ntpd]
-x Ordinarily, if the time is to be adjusted more than 128 ms, it is
stepped, not gradually slewed. This option forces the time to be
slewed in all cases. Note: since the slew rate is limited to 0.5
ms/s, each second of adjustment requires an amortization interval
of 2000 s. Thus, an adjustment of many seconds can take hours or
days to amortize.
