If you have enabled makestep, it doesn't matter how large is the
offset. But it does matter how stable it is. The default value of
maxdistance is 3 seconds, which includes the jitter of the refclock.
In your case the reported distance (the +/- value) was in hours.

Can you please post the refclocks and statistics logs? We should
better see what is happening.
