Einstein wrote something like 'time is what clocks say'.

And I had rejected this idea, because it would in effect exchange the 
natural phenomenon with the reading of a measuring device.

I regard physical quantities as attributes of some system or object, 
while emasuring devices as man-made objects, which belong to the realm 
of the observer.
