The recent patch by Jim Houston explains the misbehaviour. It seems the
ntp daemon uses ADJ_OFFSET_SINGLESHOT for time adjustments, which is
rather coarse-grained. By adding proper PPS support one should be able to
get a more stable clock, but it's better done by someone who has the
hardware to test this.
