What is time?

Do we even know? After looking around on google i don't see many answers that give a clear definition of what time is. Is time our 3 dimensional universe's movement through another dimension? I also cant get a good clear definition of "what is spacetime" everything just says it's a combination of space and time. well I fucking get that, but what does that even mean?

incorrect.

A circle made of atoms vibrates and changes size with tempature. It also is not infinitly divisible. A theoretical math circle can be dividted into .0000onehundredzeros00001 units. A real circle of matter cannot be.
