Time is a man-made unit of commensurability to measure change in the physical world. It is useful in coordination, measurement (with the goal of drawing patterns), etc. but it is no more “real” than a yardstick. A yardstick or other measure of the physical world is merely a reference point with which we can more precisely communicate information with one another, and is not in and of itself a facet of nature outside of man’s conception.

TIME

1 – The rate(velocity) of entropic change in the universe, at current density and rates of expansion, at our current velocity relative to others.

2 – Human perception of the order of episodes (memories) of change in the universe.

3 – A standard measurement of the rate entropic change in the universe at human scale.

4 – We do not yet know if time has any meaning prior to the big bang, or when the universe has sufficiently cooled that expansion has ceased, or what occurs after expansion has ceased.

CYCLICALITY

Early man was unable to perceive changes other than cyclical, because he lacked methods of recording events such that he could perceive development (progress).
