Is time an invention or a discovery?

Time is a discovery, since it seems to be a universal law of physics.

The ways we measure time are inventions.

"Physical processes at the microscopic level are believed to be either entirely or mostly time-symmetric: if the direction of time were to reverse, the theoretical statements that describe them would remain true" doesn't that statement mean it's *not* a law of physics?

My understanding is that entropy is not time-symmetric. The quote above is definitely confusing in that context. Ultimately I think that entropy is the only reason why time IS a law of physics.

What does “Time is a law of physics” even mean?
