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

I use:

var duration = moment.duration("09:30");
var str = moment(duration._data).format("HH:mm");

And I get "09:30" in var str.

Answer 2

If all hours must be displayed (more than 24) and if '0' before hours is not necessary, then formatting can be done with a short line of code:

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

Answer 3

moment.duration(x).format() has been deprecated. You can usemoment.utc(4366589).format("HH:mm:ss") to get the desired response.

console.log(moment.utc(4366589).format("HH:mm:ss"))

Answer 4

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

Answer 5

convert duration to ms and then to moment:

moment.utc(duration.as('milliseconds')).format('HH:mm:ss')

Answer 6

To format moment duration to string

var duration = moment.duration(86400000); //value in milliseconds
var hours = duration.hours();
var minutes = duration.minutes();
var seconds = duration.seconds();
var milliseconds = duration.milliseconds();

var date = moment().hours(hours).minutes(minutes).seconds(seconds).millisecond(milliseconds);
if (is12hr){
    return date.format("hh:mm:ss a");
}else{
    return date.format("HH:mm:ss");
}
