Dick, basicly what we mean by time is just a ratio of rates of periodic events in different locations (or in the same location). And thus it (time) exists independent of our senses. Periodic events happen to be relativisticly invariant - symmetric versus shifts in velocity of reference system (= independent on motion of reference system). Thus the Lorents transformations and all relativities.

Defined this way time is completely independent from our mental models - thus has the same sense for anyone in Universe. Thus very convenient parameter to describe events in Universe.

Is there a need to define it different way and then to think what sense does the new definition of time have?
