I have read a lot of Asimov, and I don't think he suggested anything like that.
You could say that the ship was moving at a fraction of lightspeed and 878 days was relativistic time inside the ship. The problem with that is that you would have to assume that at least 50.000 years had passed for the Empire while the ship arrived at destination, and I don't think the way the series is going it looks like that much time passed, but maybe I'm wrong.
Another option is that the ship has an Alcubierre warp drive. This doesn't require jumping, and it's theoretically feasible within the existing physics framework.
A third option is that the ship is using wormholes, that are in many ways equivalent to jumping.
I don't remember Asimov stories with warp drives or wormholes, but I could be wrong.
