Well before we get to that point, let's try to figure out what the digits are. Assuming your displays are oriented as HHMM, then these definitions:
const int Digit_1 = 11; // Digital Pin 11 on Arduino controls the Mins Tens Digit (Sev Seg 10)
const int Digit_2 = 12; // Digital Pin 12 on Arduino controls the Hrs Tens Digit (Sev Seg 10)
const int Digit_3 = 9; // Digital Pin 9 on Arduino controls the Hrs Ones Digit (Sev Seg 5)
const int Digit_4 = 10; // Digital Pin 10 on Arduino controls the Mins Ones Digit (Sev Seg 5)
would produce "2314" if the code works correctly. So lets first try to see why you are getting "1214". Are the digits actually wired according to the above definitions?
