I know there are references of ships going into the warp and coming out, only to find that longer time (sometimes a LOT longer) has passed outside the warp: A ship goes in, and everyone on board feels like a week has passed, but when they exit they find 10 years have passed in realspace...
Has there ever been a canonical reference to the opposite? That a ship spends a long period of time in the warp (which has its own problems, I accept - but that's not the point of this exercise) - but when it jumps out, hardly any time has passed in the real world? A ship spends 10 years in the warp (ACK!) and when it leaves, only 1 week has passed...
Just playing with some ideas....
