A friend of mine is fond of pointing out that time travel is BS because the planet and all matter is always moving, so that, when you time travel, you will likely end up in the vacuum of space, or if you are really lucky, inside the solid rock of some planet.

In GoldenSword space-time magic, all locations are relative to the center of mass of wherever your local gravity comes from. If you are on earth at a specific longitude and latitude, this does not change in relation to the earth's center of mass (which also spins), so straight up time travel is possible from one 4-dimensional time-space location to another, because the 3-D space components do not change.
