Some nostalgia of a more recent vintage: Ingwit and others’ concept art for the Zybourne Clock.
When the object enters the timestream, time begins to correct itself. Let me use this example: Imagine four balls on the edge of a cliff. Say a direct copy of the ball nearest the cliff is sent to the back of the line of balls and takes the place of the first ball. The formerly first ball becomes the second, the second becomes the third, and the fourth falls off the cliff. Time works the same way.
