What is time?

What is time?

I have a system with just 2 states and it transitions between them constantly. I'll call this system a "clock" and one transition a "tick".

Now I have another system that I'm trying to study. It makes just one big transition.

So while the system makes one big transition how many ticks does my clock make?

The answer is called time.

All I'm doing is comparing two systems, the one I'm studying and a reference system.

If we take this as a definition of time then such things as "time travel" are difficult to explain. Actually, difficult to conceive. Actually, non existent.
