What is time?

That's an interesting definition. Although time can be measured, I’m not sure the measurement of time is the same as time itself. You measure time by comparing change in one location in space with change in another location, like measuring the change of the hands of a clock compared to the motion of something else through space. But I don’t think time is the measurement itself. I think it may be something more intrinsic.
@Pat measurement of speed is also not speed it self. Both time and velocity are concepts , so systemic.
