Convert milliseconds to hours and minutes using Momentjs

Question

I am new to Momentjs. I am trying to use it to convert milliseconds to hours and minutes. Below, x is milliseconds

x = 433276000
var y = moment.duration(x, \         


        

Answer 1

I ended up doing this...

var x = 433276000
var tempTime = moment.duration(x);
var y = tempTime.hours() + tempTime.minutes();

Answer 2

Using the moment-duration-format plugin:

moment.duration(ms).format("h:mm")

Answer 3

This seems unsupported per this SO. Following this github issue, there's a moment-to-countdown plugin that you may be able to use.

But it seems you may want Countdown.js for this in the first place.

countdown(0, 433276000, countdown.HOURS | countdown.MINUTES).toString();

Note this does not take into account leap seconds, or leap anything for that matter, as it fixes to the Unix epoch (so it's not a pure time interval).

Answer 4

There really is no need to use Moment for this operation.

It can be written in a single line:

var hours = Math.round((450616708 / 1000 / 60 / 60) * 100) / 100;

or as function:

function millisecondsToHours(ms){
  return Math.round((ms / 1000 / 60 / 60) * 100) / 100;
}

Answer 5

There is an easier way to achieve what you want.

This

moment('2000-01-01 00:00:00').add(moment.duration(1000)).format('HH:mm:ss');

Will output this

00:00:01

Not the fanciest, I know, but it is 100% pure moment js.

edit: Doesn't work for periods longer than 24h

Answer 6

Here is a function that formats it for you into a string.

function ms_to_str(val) {

    let tempTime = moment.duration(val),
        timeObj = {
            years: tempTime.years(),
            months: tempTime.months(),
            days: tempTime.days(),
            hrs: tempTime.hours(),
            mins: tempTime.minutes(),
            secs: tempTime.seconds(),
            ms: tempTime.milliseconds()
        },

        timeArr = [];

    for (let k in timeObj) {
        if (Number(timeObj[k]) > 0) {
            timeArr.push(`${timeObj[k]} ${k}`)
        }
    }

    return timeArr.join(', ');
}

Then simply call ms_to_str(2443253) which returns 40 mins, 43 secs, 253 ms.

If you do not need to show milliseconds, simply comment off the ms: tempTime.milliseconds().toString().padStart(3, '0') line.
