Minecraft Timed Redstone Clock

This is a device that you can actually tell minecraft time. It is very reliable and uses 4 dispensers that will trigger each other once an item disappears after 5 minutes. A minecraft day is 20 minutes long so in theory, if you have 4 dispensers with blocks that disappear every 5 minutes, that equals 20 minutes! You can customize the screen to make it whatever you want, I just did day and night and like a red wool for sunrise/set. You can place this simple design in a giant clock tower, or in your fancy home!
