    I have two timestamps and I need difference between them in hours. How to calculate them.

    var resolution
var EndTime = 1541092163000
var StartTime = 1541077763000
resolution = slaEndTime - slaStartTime
var resolutionTime = ((resolution / (1000 * 60)) % 60)

    • I'm assuming the sla prefix is an issue with copying your code to SO? – George Commented Nov 21, 2018 at 13:26

    • 2 That's not a duplicate... the time here is not in 24 hour format – Oram Commented Nov 21, 2018 at 13:28
    • First convert both to same time format, may be to IST, then convert to milliseconds and find the difference – Raja Mohamed Commented Nov 21, 2018 at 13:30

    Reset to default 8

    You just need to divide rather than do times and modulus

    /1000 will convert it to seconds

    the first /60 will convert to minutes

    and the last /60 hours

    var resolution
var EndTime = 1541092163000
var StartTime = 1541077763000
resolution = EndTime - StartTime
var resolutionTime = (((resolution / 1000) / 60)/ 60)
console.log(resolutionTime)

    Or you can use momentjs https://momentjs./

    See the snippet below. You need to divide by 1000 then by 60 and then by 60 again to get the hours. In short you need do divide by 1000*60*60=3600000.

    var endTime = 1541092163000;
var startTime = 1541077763000;
var differenceInMiliseconds = endTime - startTime;
var differenceInSeconds = differenceInMiliseconds / 1000;
var differenceInMinutes = differenceInSeconds / 60;
var differenceInHours = differenceInMinutes / 60;
console.log(differenceInHours);

// or in short
console.log((endTime - startTime) / 3600000);

    have you tried to do this ?

    var resolution
var EndTime = 1541092163000
var StartTime = 1541077763000
var resolution = EndTime - StartTime
var resolutionTime = (parseFloat(resolution) / (60000*60) ) 
console.log(resolutionTime)

    Save yourself from manual dates manipulation insanity and use moment.js

    const moment = require('moment');

var EndTime = 1541092163000
var StartTime = 1541077763000
var resolution = moment(EndTime - StartTime).asHours();

    This approach helped to get a basic hours, minutes, seconds breakdown.

    const Duration = (difference) => {
    let secondsInMiliseconds    = 1000, 
        minutesInMiliseconds    = 60 * secondsInMiliseconds,
        hoursInMiliseconds      = 60 * minutesInMiliseconds;

    var differenceInHours       = difference / hoursInMiliseconds,
         differenceInMinutes    = differenceInHours     % 1 * 60,
         differenceInSeconds    = differenceInMinutes   % 1 * 60;
    return {
        "hours"   : Math.floor(differenceInHours),
        "minutes" : Math.floor(differenceInMinutes),
        "seconds" : Math.floor(differenceInSeconds)
    }
}
let aLittleWhileAgo = (new Date()-10000000)
let now = new Date();
console.log(Duration(now-aLittleWhileAgo))

    Use ms to calculate the difference between two timestamps

    const ms = require('ms');

var EndTime = 1541092163000;
var StartTime = 1541077763000;

ms( EndTime - StartTime) //return 4h
