Answer 1

I would also go with the moment.js but you could do:

function time_diff(t1, t2) {
   var parts = t1.split(':');
   var d1 = new Date(0, 0, 0, parts[0], parts[1], parts[2]);
   parts = t2.split(':');
   var d2 = new Date(new Date(0, 0, 0, parts[0], parts[1], parts[2]) - d1);
   // this would also work
   // d2.toTimeString().substr(0, d2.toTimeString().indexOf(' '));
   return (d2.getHours() + ':' + d2.getMinutes() + ':' + d2.getSeconds());
}
