You can always teleport stuff through a wormhole when the two ends are 20 years apartm, duh.
We have to explain everything here ;-)

At the risk of freaking you out, wormholes also play in space dimension, not in time :)
Don't forget time dilation. If you move one end of the wormhole through space, both ends will be off in time too. It's more noticeable if you move it in relativistic speeds, but anything very fast should do the trick quite well.
