Stove/Furnace work faster if everyone sleeps.

When it is night time and everyone is sleeping time jumps to the next morning. If you have a stack of something cooking in the furnace. When you wake up it's still cooking the same piece it was on before the night cycle finished. Depending on how far though the night it has been since you started to sleep, so many items should be cooked in the meantime. Example: if I put a full stack of raw iron in the furnace and the beginning of night and sleep, when I wake up and check in the morning at least half of the stack should be completed. Not just 2 iron
