That's "relatively" easy to do. Get in a space ship that could quickly get to a fraction of c, travel for a short amount of time and then return back to the starting point. You would have traveled to the future from the point of view of some one at the starting point.

This is actually harder to do in practice and is a common misunderstanding of the twin paradox, which is resolved by incorporating acceleration into the model.

You'll have better luck with gravity wells.

It’s not only not a misunderstanding of the twin paradox, but is correct and verified by experiment.
