  No, some are talking about how it needs to detect gravitation from other planets.

  That has nothing to do with a time machine working on earth.

    The time machine would use gravity so it can arrive at the same relative position in a different time. But that only gets you on the planet, not the same position on the planet.

    How would rotational movement be accounted for in a generic way?

      I don’t know how it would be accounted for in your imagine time-machine. Because they don’t exist.

      What I do know. Is that you don’t need gravity to “detect” earths rotational speed. Because we already know what it is.

        We know the rotational speed, but this time machine wouldn’t.
