Tutorials/Day and night detector

Day and Night detector's are mechanisms in which allows for the player to detect what time of day it is. The concept is based on the fact that how water at night turns grass into dirt and vice-versa. With this, it allows use of a BUD to trigger redstone contraptions.

Day Counter
Using the new light detector, one can set up a day counter; used for survival challenges, and adventure maps.| All one needs to do, is use redstone to connect a light detector and piston, the piston being in front of a tower of sand or gravel, which is in front of a ledge, then when daylight hits the detector, it powers the piston pushing the sand or gravel off of the ledge, giving a count on the number of days it has been since a point in     time. This can also be used to create a time delay mechanism. By adding a branching redstone wire and simple inversion circuit to a lowered piston, when a certain day number is reached, the moment the light detector senses darkness, it will activate the inverter, activating the second piston hitting the sand block representing the desired number of days passed off of the stack, down to a torch placed on the wall, over a wooden pressure plate, sending off a signal to you time delayed device.
