Time is a series of "nows" linked front to back. To me it is a necessary property of everything. My speculation is that mass itself is change in the electric and magnetic amplitude of a local area of space over a period of time. This was a popular idea a little over a hundred years ago. In Einstein's words

The final irreducible constituent of all physical reality is the electromagnetic field.
We don't think that way now; but that old idea has never been falsified.

Nice statement. Quite powerful, whoever wrote that.

Anyways, time doesn't exist as a force of nature. It's just events of the physical world. A good example are the arms of a clock. They are just events.

Time is events. [^]

Time is a one way street.
At least macroscopically.
