This is getting a bit far from antennas, but the way to know the uncertainty
in knowing time is to have multiple clocks. NBS (whatever it now calls
itself) has a bunch of clocks that are compared to each other.
When I was young (and WWV was back East) the uncertainty indicated from
multiple clocks was a few parts in ten to the eighth power. Today, that
uncertainty is a few parts in ten to the 13th power! It takes multiple
clocks to know the uncertainty.

A man with a watch knows the time.

A man with two watches is never sure......
