You missed the point, Jim. Calculating the age of the
universe, ever and ever more accurately, with a standard
that may be continuously changing is technical insanity.

The point you're missing is that the standard isn't changing with
respect to the frame in which the observations are made. We're
accurately measuring what we're observing in our reference frame -
unless of course you're prepared to prove otherwise.
