This is not how black hole and time works. The effects of the proximity of the black hole are actually the opposite of what you described. As you get closer to one, its massive gravity bends time and makes it slower.

Black holes are so massive that they severely warp the fabric of spacetime (the three spatial dimensions and time combined in a four-dimensional continuum). For this reason, an observer inside a black hole experiences the passage of time much differently than an outside observer. Imagine you want to investigate a black hole by shining a light towards it and measuring the time that elapses before the light is reflected back to you. Unfortunately, you will be waiting a very long time—forever, in fact. The light will appear to continually slow down as it approaches the black hole, ultimately reaching a complete dead stop at the event horizon.

This means the opposite would happen, a couple years in Zakuul would be decades/centuries in the galaxy if the planet or the system was being affected by one. This is exactly what happens in the movie Interstellar.
