A coin cell powered Real Time Clock Calendar keeps track of the time and date when the unit in not powered.
The Matrix Clock can also play musical alarms that can be easily reprogrammed with different tunes. Due to its compact form factor the Matrix clock could be fitted in any number of housings even a pocket watch style housing. If portability is desirable then the unit can be battery powered. A sleep function is available (by taking one of the expansion pins to ground) in order to extend battery life.
