How to convert an NSTimeInterval (seconds) into minutes

Question

I\'ve got an amount of seconds that passed from a certain event. It\'s stored in a NSTimeInterval data type.

I want to convert it into

Answer 1

All of these look more complicated than they need to be! Here is a short and sweet way to convert a time interval into hours, minutes and seconds:

NSTimeInterval timeInterval = 326.4;
long seconds = lroundf(timeInterval); // Since modulo operator (%) below needs int or long

int hour = seconds / 3600;
int mins = (seconds % 3600) / 60;
int secs = seconds % 60;

Note when you put a float into an int, you get floor() automatically, but you can add it to the first two if if makes you feel better :-)
