Time travel is possible to some extent because time slows down for you as your speed increases. Although it happens every time you take a walk, it's to such a tiny degree that no-one ever notices. Start talking about speeds of fractions of the speed of light, though, and it is very noticeable indeed.
Having said that, this time dilation effect was measured earlier this year with atomic clocks on vehicles travelling no faster than normal cars.
If we had the technology, it'd be perfectly possible for you to travel a few years away from earth and then back again, to find that hundreds of years have passed here. Unfortunately, the only way this could currently be done is with a nuclear device and a treaty was signed preventing nuclear reactions as part of space travel. It's a shame the same treating didn't prevent the dumping of human waste matter from every shuttle and station that's been up there. There's now so much crap up there that everything returning to earth comes back with a thin film of sewage.

If you travel twice around the galaxy (or the universe, no idea which) at the speed of light it would take you 2yrs but on earth it would be 50 yrs
Also, an atomic clock was flown about in a plane for a bit and was one millisecond ahead of the clock on the ground...
