moment unix timestamp formats wrong date

Question

I want to convert an Unix milliseconds timestamp to readable date.

My timestamp is 1525772511140. The correct output should be something like: 29-05-2018 9:41:51AM

Now my code returns a wrong date: 31-10-50319 03:10...

code:

var timeStamp = new Date(1525772511140 * 1000);
var date = moment(timeStamp).format('DD-MM-YYYY HH:mm');
console.log(date);

Answer 1

You can simply use moment(Number):

Similar to new Date(Number), you can create a moment by passing an integer value representing the number of milliseconds since the Unix Epoch (Jan 1 1970 12AM UTC)

var date = moment(1525772511140).format('DD-MM-YYYY HH:mm');
console.log(date);
// with seconds and AM/PM
date = moment(1525772511140).format('DD-MM-YYYY hh:mm:ss A');
console.log(date);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.22.1/moment.min.js"></script>

Native JavaScript solution (without moment.js) :

var d = new Date(1525772511140);
console.log(
  ("0" + d.getDate()).slice(-2) + '-' +
  ("0" + (d.getMonth()+1)).slice(-2) + '-' + 
  d.getFullYear() + ' ' +
  d.getHours() + ':' +
  d.getMinutes()
);

Answer 2

Just remove the *1000 from your statement and it works:

var timeStamp = new Date(1525772511140);
var date = moment(timeStamp).format('DD-MM-YYYY HH:mm');
console.log(date);

The timestamp is already in milliseconds so no need to multiply by 1000.
