Have you ever needed some random hostile mob drop but its the middle of the day or you just don't have time to waste sitting around waiting for night, if so have i got the mod for you. To change time you require 4 obsidian and a block of redstone a clock-like recipe. This mod can be and is very useful for one of the most annoying parts of minecraft. Time is an important resource we have and the ability change the amount of time something takes makes it easier to use.
