And right there you have hit upon another problem with fictional Time Travel machines...THE TIME MACHINE <snip> though that guy's machine worked fine, it never moved from it starting point, except in the 4th dimension.
Any point on the Earth rotates at over 1000 miles per hour, taking 24 hours, our day, to make one rotation. The Earth also "wobbles" on its polar axis.
The Earth revolves around the Sun, taking one year to make one revolution. This orbit is both eccentric and elliptical.
Our solar system is moving towards the constellation Hercules, and it is also currently moving upwards, at 90 degrees to the plane of the Milky Way.
At he same time our solar system revolves around the Milky Way taking 225 million years to make one rotation around the galaxy.
Space itself is expanding and our region of Space has been moving outwards since the Big Bang.
Even if you could calculate all of this accurately, you still have the problem of pin pointing a reference point.
The TARDIS (Time And Relative Dimensions In Space) somehow manages to do all of this, for which it is due some little respect.
Gregory Benfold used the idea of the Earth moving in space in time best in the novel Timescape, but to say more would be spoiling it.
Edit: And I forgot to calculate for Continental Drift - now I've accidently re-materialised 2ft out inside a wall!
