Sleep. In later stages of the game, you can go out at night in biomes that you have conquered, even during thunderstorms. (A good thunderstorm at night is the best time to chop wood)

The reason you have been filing at night is to make the day free for building and exploration. It takes no time to dump your stuff into the bbus and if it's not full, you're done.

When it does get full of some item, you can defer filing until night if you have some sort of overflow chest. Any adjacent chest that is not full will do.
