Here's the XC32 project. It is pretty crude, so sorry about the lack of comments, but it should be pretty straight forward. The DateTime library doesn't support decrement of time as I only needed increments, but can be pretty easily added.
Basically there's an interrupt trigger on the UART (GPS) that updates the led modules. There is supposed to be a DS3232 backup when lacking GPS data, but didn't need to implement it as it works pretty good once it gets a lock. There are still some kinks but nothing mayor
*edit* managed to introduce a bug cleaning the code dealing with the ds3232 or gps. Clock suddenly stopped ticking on the night stand. I will have to go through it and post an update
