the Roommate Agreement was signed.
Then they wait and get disappointed that they don't re-appear 5 minutes after signing the contact.
So many TV shows have demonstrated how paradoxes would be created if Time Travel "Backwards" would be able to occur. It is fantasy.
Of course, Time Travel "Forwards" happens all the time whenever some travels at speeds relative to each other, according to Einstein's Special Relativity.
As an exaggerated example, identical twin Astronauts Mark and Scott Kelly, with Scott being on the International Space Station traveling at 17.5KMPH for about 520 days. At the end of this, Scott was about 6 minutes younger (or 6 minutes into the future) relative to his identical twin Mark.
Granted this was a bit more gradual than you may have been thinking (step into a box and being propelled into another time) but you don't have to totally leave town and communication. You can jump on a faster conveyor belt to the future, but you can't go back.
The movie Intersteller had an interesting take. Matthew McConaughey, and a couple of Astronauts, went to a planet with a large gravitational field, and were propelled into the future (without their aging) by a large number of years. The only problem with the script was that they should have also "felt" the gravity of the planet that affected them if they were to age that much. But, it was all in good fun.
