title: How can I get the amound of seconds from a NSDate ("hh:mm:ss") and vice versa
body: <p>I am trying to make a timer and yes I have looked at NSTimer and it is not what I'm looking for, I basically need a way to convert a NSDate in the format of ("hh:mm:ss") into the amount of seconds that would be in this. And then I need a way to do the opposite so convert the seconds to the amount of hours, minutes and leftover seconds from that.</p>
