Convert systematic date to formatted date

Question

I want to convert systematic date into readable date format. However when I pass systematic date as argument to date constructor I get Invalid date response. How to do this properly in order to display formatted date such as dd-mm-yyyy for GMT+2 ?

var date = message.date; // => 1466663308000
        var dateObject = new Date(date);
        console.log(dateObject);

Console output:

Invalid Date

Are you certain `message.date` is 1466663308000? Looks good to me, if so. — Lee Kowalkowski, Sep 05 '16 at 13:30
Is it a string or a number? That value works fine as a number, but not if it's a string. What happens when you try `new Date(+date)`? — Pointy, Sep 05 '16 at 13:30

You have to make sure the timestamp value is a number and not a string:

    var date = message.date; 
    var dateObject = new Date(+date); // note the +
    console.log(dateObject);

Once you've got a valid date, there are many other questions here about formatting dates.

I tried the code, it is absolutely correct. I can get the correct date

var d=new Date(1466663308000);
document.write(d);

But I tried another way:

var x = "1466663308000";
var d=new Date(x);
document.write(d);

I got the "Invalid date", so I guess, message.date should be a string, please try to long(message.date).

The issue was actually because of datatype (string rather than int) – Kunok Sep 05 '16 at 13:37
