Not sure why it added an empty line between each line...
after compiling run with
./time
It will ask you to enter time (HH:MM:SS) and then so the equal/greater crap. It uses only c++ so you can remove
#include "stdio.h"
from the top.
Also at the end there is some test code for the "operator-". You can remove it or print it out. operator-/operator+/operator+= and operator-= are all implemented
