Sorry, I should have been more explicit. What you say assumes your clock is setup correctly and operating as expected. How do you know that everything is correct? An obvious example is triggering off the wrong edge of the PPS signal. You can also have a fudge time1 when you don't need one, or have the wrong value when you do need one. You can use systems on the net as a sanity check. They may not be great, but they are available for not much cost/effort. If you plot offset vs rtt and the blob at the point of the wedge doesn't overlap an offset of 0 something interesting is going on. Aside from at offset in your local clock, it might be asymmetric network paths. (or maybe the remote clock is setup wrong) -- The suespammers.org mail server is located in California.
