How to use format() on a moment.js duration?

Question

Is there any way I can use the moment.js format method on duration objects? I can\'t find it anywhere in the docs and it doesn\'t seen to be an attribute on du

Answer 1

if diff is a moment

var diff = moment(20111031) - moment(20111010);
var formated1 = moment(diff).format("hh:mm:ss");
console.log("format 1: "+formated1);

Answer 2

const duration = moment.duration(62, 'hours');
const n = 24 * 60 * 60 * 1000;
const days = Math.floor(duration / n);
const str = moment.utc(duration % n).format('H [h] mm [min] ss [s]');
console.log(`${days > 0 ? `${days} ${days == 1 ? 'day' : 'days'} ` : ''}${str}`);

Prints:

2 days 14 h 00 min 00 s

If you use Angular >2, I made a Pipe inspired by @hai-alaluf answer.

import {Pipe, PipeTransform} from "@angular/core";

@Pipe({
  name: "duration",
})

export class DurationPipe implements PipeTransform {

  public transform(value: any, args?: any): any {

    // secs to ms
    value = value * 1000;
    const days = Math.floor(value / 86400000);
    value = value % 86400000;
    const hours = Math.floor(value / 3600000);
    value = value % 3600000;
    const minutes = Math.floor(value / 60000);
    value = value % 60000;
    const seconds = Math.floor(value / 1000);
    return (days ? days + " days " : "") +
      (hours ? hours + " hours " : "") +
      (minutes ? minutes + " minutes " : "") +
      (seconds ? seconds + " seconds " : "") +
      (!days && !hours && !minutes && !seconds ? 0 : "");
  }
}

Answer 4

I needed to do this for work as a requirement to display the hours in this format. At first I tried this.

moment.utc(totalMilliseconds).format("HH:mm:ss")

However anything over 24 hours and the hours reset to 0. But the minutes and seconds were accurate. So I used only that part for the minutes and seconds.

var minutesSeconds = moment.utc(totalMilliseconds).format("mm:ss")

Now all I need is the total hours.

var hours = moment.duration(totalMilliseconds).asHours().toFixed()

And to get that format that we all want we just glue it together.

var formatted = hours + ":" + minutesSeconds

if totalMilliseconds is 894600000 this will return 249:30:00.

Hope that helped. Leave any questions in the comments. ;)
