Motion can simply be the movement of objects. This doesn't imply that time has to be an object.
I'm not saying time is an object. Perhaps poor wording on my behalf. Put it this way:
A ball is moving at a given speed in a given direction. If it is 1m from its starting point during a single frame, and then 1.1m from its starting point in another frame, then the ball's position changed. Such a change is called motion, obviously. However, if you remove this progression of frames, it is impossible for anything to move. This progression we refer to as time, and use it to measure the order of events.
If we call such a progression time, and if it's impossible to have motion without this progression, thus it is impossible to have motion without time.

That's just recursion.
