Just thinking of wild ideas, what if due to the Yami Yami no Mi powers, one part (or half) of the island where Ace and BB fought will always be darkness. Sunshine just could not reach to the area, despite there's no object or thick cloud to block the sun. Hence its always nighttime (no sunshine). I aware its no logic but that would be cool if it does happen in the OP universe.
