  What? This whole thread is discussing how a time only device is useless.

    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.
