For some reason the times that I am sending to the Jump class are not incrementing even after implenting a sleep(10) call? Maybe as part of the testing scaffold implement a file parsing function and create a sample device logfile, then send what is in it to the Jump class. This would allow to create an entire dummy jump without having to do it in code...Also, better idea: instead of sec_dec look into using other time structs like timespec (<ctime>).
