[time-nuts] Stability vs. Accuracy

[Richard Dabney]

I'm not a scientist or engineer but have a question to those of you who are.

The many recent posts regarding the GPSDOs and comparisons between the various ones  have been comparing stability. How about accuracy compared with the national frequency standard?
Are stability and accuracy the same? Stability to E-13.5 with the Thunderbolt. How close to
perfect time and frequency?............  Thanks...Dick W5UFZ    FMT-nut
