Time is simply, the sequence of events. Almost all events, have duration, because of the limited field displacement velocity. This limited velocity, along with variable distances, gives a train of time sequence.....to object interaction. If field velocity were instant, all events would have happened at the same time, and all interactions would have been completed. All time and motion would be done and over.
It's that simple and there is no magic to it. Time is not related, nor is it a property of space. Time is a property of motion. Space is simply an empty area, allowing motion.
