I don't have one handy, BUT I saw this SAME problem across oh, 20 machines.
Every one.  Every time.

And oh, by the way, when one of them (mine) was upgraded to the newest ntpd,
it *WENT AWAY*.  Thus, I think its quite reasonable to say its not the clock
and must be the code (since the hardware could not have magically changed
:-)

Had one at MCS (Spectracom WWV receiver), but its there and I'm here.  It
appears from their strata change (from 1 to 2; I chime off them) that they 
turned it off.  I should have taken it with me when I left :-)

BTW, speaking of which, does anyone know of a reasonably-cheap GPS receiver
that (1) has an external-able antenna that will work with somewhere between
50 and 100 feet of lead, and (2) has the appropriate pps outputs and such
so it can be used for this?
