[time-nuts] Primary frequency standard

[cdelect at juno.com]

In reference to:

"It would be cool to say one has a "primary standard", .... So, I think
we should be careful with the term, it's get thrown around too lightly."

Any of the hobby grade used Cesium standards is actually a Primary
frequency standard as it does meet the definition of:

A frequency source that meets national standards for accuracy and
operates without the need for calibration against an external standard.

They ARE able to meet their accuracy specs without calibration against an
external standard.

The definition does not exclude them.

I realize that Metrology usage may be different but the definition makes
no judgement as to how performance levels!
