The current time is displayed using an Arduino Uno, SparkFun GPS Shield, EM406A GPS Receiver, and 7-Segment Serial Display - Red. This code parses the GPS data when there is a satellite lock and outputs the data to a 7-segment serial display using software serial pins. The clock is adjust for Mountain Daylight Time (MDT) with an optional mode for daylight savings with the press of a latching button, jumper wire, or switch. There is a status LED indicator for the MDT to indicate whether it is AM or PM.
