Night carrier doctrine and an earlier Pearl Harbor strike

A Japanese navy trained for night carrier operations would have little reason to wait for daylight at Pearl Harbor, increasing the defenders' difficulties.

Question

How would Japanese night-carrier doctrine and training change the opening of the Pacific War?

Short answer

Pearl Harbor could be attacked in darkness instead of waiting for morning, making the initial defence still more difficult.

Notes

The counterfactual gives the Imperial Japanese Navy night-carrier doctrine, suitable aircraft and pilot training before the Pacific War. Its immediate operational consequence is a different opening at Pearl Harbor: the strike need not wait until 7 a.m. on Sunday. Aircraft arriving in darkness would confront air defences even less prepared than they were historically. The wider scenario changes so many assumptions that only the early consequences can be traced with confidence. Doctrine and training can alter operational timing even before additional carriers change the scale of an attack.
