You can enter your location (not well covered) to get an idea where your place would have been X million years ago.

If your TARDIS doesn’t materialize underwater or inside solid rock.
If you go into the future, you may find it in the middle of a freeway, about to get hit by an electric 18 wheeler. Or perhaps in a war zone.

My luck, I'd land right in the middle of a T-rex nest. 😳Being able to check my arrival location will be handy when I get my time machine working.

I can recommend the BBC series 'Earth' hosted by Chris Packham. Superb!
fun website. Interesting for UK to see how it was above then below then above sea level many times.
I watched the last program of the 'Earth' series this evening and was rather disappointed. I don't tolerate Chris Packham for long anyway, but this program skipped over about 50 million interesting years to spend 15 minutes being santimonious about modern life at the end.

Back in a while.
The fact that the Earth, Solar System and the entire Milky Way Galaxy are hurtling through space may explain why time travellers have never come back to report their success!

I want you home in time for dinner, young man.Back in a while.
I haven’t left yet. I hadn’t charged the batteries in quite a while so I can’t try until tomorrow.
Galu: can you imagine returning, wondering where your planet went and coming to grips with your momentary lapse of reason?
Jeff, tonight is leftovers. Then we head to the mall as we don’t have A/C here. Hope you’re doing okay in the heat.

This is all fine and dandy, but I want to see 5 million years into the future. I want to know where my fossilized skeleton will be when the United States Postal Service finally delivers my package!
Well, in addition to creating a mechanism for time travel, a "relative spatiality compensator" must be fabricated. The earth rotates on its axis, the Earth undergoes precession, the Earth orbits the sun, the solar system "orbits" along one of the spiral arm of our Milky way galaxy...Calculating an exact place in space at any one time in the past or future would be immensely difficult...without this precision, one could easily "materialize" back in say the 1920s, but 330 feet up in the air...

No A/C here either, so the nights are a bit rough, but otherwise fine. Pretty sure it will be a bit hotter at your place. Looks like the temps will peak today, and then taper off tomorrow.Then we head to the mall as we don’t have A/C here. Hope you’re doing okay in the heat.
Last night was chicken pizza on the BBQ.

We love dull. Things are a little too spicy here for us old guys right now.
I pity those having to work all day in it. I see some sites shutting down around 2pm.

I don't mind as long as fish & chips are on the menu.come to england, our weather is as dull as our food at the moment.
I thought relativity meant it all depends on the reference frame and coordinate system. Like this application should be able to define a system that accounts for the tectonic shifts so that the selected location remains at [0,0,0,t].Well, in addition to creating a mechanism for time travel, a "relative spatiality compensator" must be fabricated.

I mean, plenty of folks' reference frame revolves around them...

The field equations of general relativity permit a closed timelike curve (CTC) along which an object can move through spacetime and eventually return to the exact same coordinates in space and time that it was at previously.
It appears that a CTC would permit a time traveler to travel into the past, but only if it is a past of which the time traveller would have always been a part. This ensures there would be no changes to the past as a result of the time traveler suddenly showing up there.
Annoyingly, if the time traveller can't change history, that would limit the dramatic tension in many science fiction stories!
The 2004 TV series Lost involved a CTC plotline where a group of characters traveled backward in time, in the hopes of altering events. However, it turned out that their actions in the past create no change in how events unfolded, as it turns out that they were always part of how those events unfolded in the first place. 🤓
