Careful.  That is "Offset", not the common sense meaning of offset, 
which might be put something like: the true error between the local 
clock and true time.

To the extent that is possible to say that "Offset" accurately 
represents offset, ntpd's algorithms are flawed, and need improving 
until "Offset" again consists only of measurement noise.  Whether they 
are actually flawed is the basis of the long running dispute between 
Unruh and Dave Mills.
