[time-nuts] How do I know my GPS stabilized oscillator is working?

My understanding is that the convention is to put the DUT on the start
and the reference on the stop (reversing the two will obviously reverse
the sign of the offset and drift) but I am not sure how widely accepted
that convention is.

I'd be really happy to have some confirmation that in fact I'm doing it
the right way.
