I believe we do have two such measures, Atomic Time measured with lasers and
such and Ephemeris Time measured from the motions and positions of solar-
system bodies with reference to General Relativity.   Atomic time was set 
up to be as consistent with Ephemeris Time as experiment would allow, but 
the ultimate agreement of the two scales in the future is really a matter
of experiment, right?

If they should be found to run on different tracks, that would no doubt be 
taken to indicate that we need to modify quantum mechanics or general 
relativity, or both.
