With the received absolution from Graynomad, I make my first move with an RTC lib for the Due, there are many stuff for the RTC in the Framework and in the Arduino IDE too.
This is my first version inspired by stimmer, really small on functions but you can Set time and Get time. I make some Wrapper Calls around the functions that i found in the IDE to make it a little bit easier to use it, the other functions like Date and Alarm will follow immediately, this is only for the first view.
B.R.
