Formatting MomentJS duration above 24 hours

Question

I would like to format a summed up total working hours e.g. 49.75 to this: 49:45.

When I use duration like this:

const         


        

Answer 1

I think you cannot use format but build it manually:

var dur = moment.duration(49.75, 'hours');
var hours = Math.floor(dur.asHours());
var mins  = Math.floor(dur.asMinutes()) - hours * 60;
var sec   = Math.floor(dur.asSeconds()) - hours * 60 * 60 - mins * 60;

var result = hours + ":" + mins + ":" + ((sec > 9) ? sec : ("0"+sec));
console.log(result); // 49:45:00

Fiddle
