That is "sort of" the idea behind using a wormhole as a time travel device.
Take one end far away, and back, at relativistic speeds.
Due to time dilation, you now have a wormhole with one end in the present and one in the future.
Traverse wormhole to move from present -> future or from future -> present.
Unfortunately we don't know how to do Step 1, or if it is even possible in the real world.
If it was, we don't know how to keep it stable in order to traverse it.
If we could do those 2 things, you would never be able to go back into the past to a time before the wormhole was created (one end only works in the
present, not the past). But presumably you could always go back as far as that, or as far into the future, for as long as the wormhole remains intact.
