Now-state is the summation of all past events,
acting on the initial state of the universe.
In this sense, time is a counting number:
counting the number of events since the big bang.
For states, the now-state is not the summation of all past states.
In this sense, time is an ordering number:
putting different states of each “same” object in order.
