I found a YouTube video showing how to build a day/night sensor. Help. This makes for much easier lampposts. So in the "middle" of the Terran planet on a 2 hour cycle it feels like days are maybe 30 minutes long and nights are 1:30. Pocket Edition Alpha; 0.2.0: Added the day-night cycle. We will continue to show them individually for version history. This Minecraft tutorial explains how to use the /daylock command with screenshots and step-by-step instructions. You can disable the day/night cycle completely using a gamerule: /gamerule doDaylightCycle false Once you have done that, you can set the time to whatever time you want using /time set
