Using the amazing moment.js library:
function humanizeDuration(input, units ) { // units is a string with possible values of y, M, w, d, h, m, s, ms var duration = moment().startOf('day').add(units, input), format = ""; if(duration.hour() > 0){ format += "H [hours] "; } if(duration.minute() > 0){ format += "m [minutes] "; } format += " s [seconds]"; return duration.format(format);}This allows you to specify any duration be it hours, minutes, seconds, mills, and returns a human readable version.
