Temporal displacement
From Memory Alpha, the free Star Trek reference.
A temporal displacement is a temporal phenomenon in which a certain element from one time period is misplaced into another time period. If not corrected, a temporal displacement could have devastating effects to the timeline.
In 2372 Benjamin Sisko was held in a temporal displacement after a warp core accident caused by a subspace inversion of the Bajoran wormhole. (DS9: "The Visitor")
