No, time is the stuff *between* ticks of the clock. The "time"
displayed is like the position of an odometer on a car... just
approximately where you are at now.

Better still events occurring at the "same place", but
successive. Like two clock ticks.

I don't follow this.

So what you are saying is the speed of light is always the
same... at any given instant. Because that is all we can
measure.
