Daylight Detector

Daylight Detectors are blocks which will probably be implemented in 1.5 "Redstone Update". The block was announced at Minecon 2012. Jeb said that the blocks would send a redstone signal with a strength depending on the amount of daylight available. It won't generate an output at night.
