In "Hyperspace" by Michio Kaku, a scenerio is sketched out which seems like it would work. You make a worm hole - he descibred how to do this, it involves something with charging two sets of plates and relies on something called the Casmir Effect, which has been observed in the lab on a small scale, but he didn't go into much more detail about it - anyway, you make a worm hole using the Casmir Effect, and you have the two ends of a wormhole right next to eachother. You then put one on a ship, and accelerate it to near-light speed, and fly it around for a while, then after 20 years or so, return it to its original position. While this one end of a worm hole was going very fast, time was compressed for it - say it was going fast enough that only 10 seconds passed for it while 20 years passed for the other end of the worm hole which did not travel. Now, you have a wormhole which has one end at point A in space, and its other end only a mile or so away, but one end is twenty years ahead of the other one. You pass through one end and come out the other end twenty years into the future. Pass the other way, and go twenty years into the past.
