Convert the time stamp UTC to IST using JavaScript

Question

I'm looking for a suitable way to convert a timestamp from UTC to IST using JavaScript DateTimeStamp "20160108120040".

The timestamp comes from an XML in my body request.

If you haven't noticed already, javascript is very bad at handling time and dates. They provide very little in the way of handling timezones and doing conversions. I usually just AJAX something to a server to be handled when needed. But you can also try [moment.js](http://momentjs.com/) I haven't used it but it comes recommended among my friends. — Squeegy, Apr 07 '16 at 20:42
Thanks for your suggestion. Even moment.js i am not aware of it how to work. will check it and try to implement in my test script. — Pramod SR, Apr 08 '16 at 09:29

First thing, take a look at JavaScript date formats and convert your input date accordingly, then you shoud take a look to the methods available in JavaScript for date manipulation (no external library required). It's pretty easy to do something like this:

var dateUTC = new Date("yourInputDateInASuitableFormat");
var dateUTC = dateUTC.getTime() 
var dateIST = new Date(dateUTC);
//date shifting for IST timezone (+5 hours and 30 minutes)
dateIST.setHours(dateIST.getHours() + 5); 
dateIST.setMinutes(dateIST.getMinutes() + 30);

Notice that `dateIST` is not "an ist date", it's just a "wrong" date that when calling `.toUTCString()` on will yield a string that's accurate in IST. The date object should only be used for that `toUTCString()` call and not be used elsewhere. – Bergi Jan 06 '18 at 17:24

use toLocaleString and provide desired timezone:

new Date("yourInputDateInASuitableFormat").toLocaleString("en-US", {timeZone: 'Asia/Kolkata'})

The above code will give date in mm/dd/yy, hh:mm:ss format. to make it dd/mm/yyyy, hh:mm:ss format which is standard for indian time - use this code :- `new Date("yourInputDateInASuitableFormat").toLocaleString("en-IN", {timeZone: 'Asia/Kolkata'})` – aumiom Apr 05 '22 at 08:52

const getISTTime = () => {
  let d = new Date()
  return d.getTime() + ( 5.5 * 60 * 60 * 1000 )
}

Based on the accepted answer

export default class DateIST extends Date {
    constructor(params) {
        super(params)
        console.log(this)
        console.log(this.toString())
        console.log(this.toLocaleString())
        console.log(this.toISOString())
    }

    toISOString() {
        var date = new Date(this)
        date.setHours(date.getHours() + 5)
        date.setMinutes(date.getMinutes() + 30)
        return date.toISOString();
    }
}

var dateIST = DateIST('...')
console.log(dateIST.toISOString())

// For comparision purposes with Date, like when used in Mongoose Schema with ISODate in MongoDB
dbCollectionModel.find({ dateMongoDB: { $lt: dateIST.toISOString() } })
