[time-nuts] OOPS on my wwv legal post

[Bob kb8tq]

Hi

A few more details about “traceability”. USNO is by statute the official source of time for the US. 
To the extent you are getting time from NIST, you are getting it “second hand”. Is that a big deal 
past the nanosecond level … not so much. It’s still true that USNO is what you need to get back 
to. If you are going to get excited about it, you need a piece of paper that shows how far off whatever
you are using is from USNO at the point you grabbed time from it. That’s how traceability works ….

My guess is that pretty much nobody anywhere worries about this to the degree of doing it properly ….
