Wouldn’t time travel boop you into space? You could go backwards let’s say, but would your let’s just go with incorporeal body remain completely still to do it? The Earth is in a wobbly orbit around the sun and rotating as well.

If you wanted to visit another time let alone place accurately you’re going to need some way to move your position as well. Otherwise you stand the chance of only being able to visit very particular times and even then, who knows what part of the world you might end up in if calculations are slightly off.

Oops I’m underground, in the sky, ocean, or just floating in space.
