Gravity can cancel out curvature of spacetime. So I would imagine that time would run at the same pace as in zero G. Also I believe you are correct about a bridging effect with colliding black holes where the two event horizons merge before the Schwarzschild radius' meet.

Edit: Just notice what you said there about merging black holes.

There would be an extension of the event horizon, not a decrease. Like a saddle, photons between the two black holes would be in a gravitational equilibrium between the two black holes but not with any other direction. So it would be in the event horizon of both, like a sitting in a saddle. Flat space between the holes but highly curved in any other direction.
