As I keep saying, offset does not accurately measure time keeping
accuracy. A low offset can mean that you are tracking traffic
variations on the LAN, or interrupt latency variations, rather than
local clock frequency variations.
It is also a pessimistic estimate of accuracy when everything is locked
up and stable.
