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

We don't think that way now; but that old idea has never been falsified.

Time is a direction.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!

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.
