Difference between two dates in hrs and mins

Question

I have two dates in millis 1513885098821 & 1513885078742. How to display the difference between above two dates in hrs and mins like 2 hrs 31 mins.
If moment have any option then its good, solution using plain javascript is also ok for me.
I tried below

moment(new Date(txn.toDate - txn.fromDate)).format('HH mm')

But it gives 05 30 result.

Output of below line is

new Date(1513885098821 - 1513885078742);

result: Thu Jan 01 1970 05:30:20 GMT+0530 (India Standard Time)

Try `moment.diff()`: https://momentjs.com/docs/#/displaying/difference/ — csp713, Jan 02 '18 at 13:36
@csp713 It will give diff either in hours or secs not both. Is there any way I am missing? — rd636377, Jan 02 '18 at 13:59

There are probably countless answers already to help you find the difference between two dates, either using moment js or simply the native javascript Date object. Since you are having difficulty though, here is an example using moment js and its diff function:

// use timestamps to create moment objects
const startDate = moment.utc(1513885098821);
const endDate = moment.utc(1513885078742);

const hourDiff = startDate.diff(endDate, 'hours');
console.log(hourDiff); // 0
const minuteDiff = startDate.diff(endDate, 'minutes');
console.log(minuteDiff); // 0
const secondDiff = startDate.diff(endDate, 'seconds');
console.log(secondDiff); // 20

console.log(`${hourDiff}hrs ${minuteDiff}mins ${secondDiff}sec`); // 0hrs 0mins 20sec

You don't need to use Date, just do this:

prettyMillisDiff(millis1, millis2) {
    let minDiff = (millis1 - millis2)/60000;
    if (minDiff < 0) {
        minDiff *= -1;
    }
    const hours = Math.floor(minDiff/60);
    const mins =  Math.floor(minDiff%60);
    console.log(`${hours} hours ${mins} mins`);
}

try splitting string from the first method.

var k=moment(new Date(txn.toDate - txn.fromDate)).format('HH mm');
var frmt=k.split(' ');
var min=frmt+'mm';
var hr=frmt+'fr';
