The universe can be represented as computation, but it appears that requires a time element. You can not define a turing machine based on just a tape - it intrinsically requires a time dynamic in the form of the moving head.

So in digital physics and computationalism, time is fundemental - it really exists and can not be abstracted away. At the most core the universe is something that changes. Described as a turing machine it consists of information (the tape) and time - the mover.

That sound right - but that leads to Option 2.

Yes your option 2 sounds almost right, but see my amendments/disagreements.
