如果你使用Angular >2，我做了一个受@hai-alaluf answer启发的Pipe。

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 : "");
  }
}

如果必须显示所有的小时(超过24小时)，如果小时之前的'0'是不必要的，那么格式化可以用一小行代码完成:

Math.floor(duration.as('h')) + moment.utc(duration.as('ms')).format(':mm:ss')

你可以使用numeric .js来格式化你的时长:

numeral(your_duration.asSeconds()).format('00:00:00') // result: hh:mm:ss

import * as moment from 'moment'
var sleep = require('sleep-promise');

(async function () {
    var t1 = new Date().getTime();
    await sleep(1000); 
    var t2 = new Date().getTime();
    var dur = moment.duration(t2-t1); 
    console.log(`${dur.hours()}h:${dur.minutes()}m:${dur.seconds()}s`);
})();

0h:0m:1s

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}`);
