This is a GPS controlled clock - a clock you truly never have to set! Using GPS and some formulas we figure out what day of the week and if we are in or out of daylight savings time.
This project uses an Arduino Uno board and several 1" alphanumeric displays, available from SparkFun Electronics.

- /Alpha_GPS_Clock_with_DST - Newer, more easy-to-use DST code.
The code is beerware; if you see me (or any other SparkFun employee) at the local, and you've found our code helpful, please buy us a round!
