Object property looking different after printing on it's own

Question

I am trying to use luxon to generate a new date using a timezone. This is my code:

var luxon = require('luxon');
luxon.Settings.defaultZoneName = 'UTC+4';
var date = luxon.DateTime.local();
console.log(date);
var now = new Date(date.ts);
console.log(now.toString());

And this is the console:

DateTime {
    ts: 2018-09-13T13:09:45.333+04:00,
        zone: UTC+4,
        locale: en-US }
Thu Sep 13 2018 11:09:45 GMT+0200 (CEST)

But if I try to access the ts property like so

var date = luxon.DateTime.local();
console.log(date.ts); // here
var now = new Date(date.ts);
console.log(now.toString());

I get this in the console:

1536830052009
Thu Sep 13 2018 11:14:12 GMT+0200 (CEST)

Why is that? Is it doing some kind of math in the background? Also it turns out this date.ts is just ignoring my timezone. How can I fix that?

Answer 1

First 1536830052009, This is your time in milliseconds,

new Date(1536830052009)
// output Thu Sep 13 2018 11:14:12 GMT+0200 (CEST)

You may want to check your timezone with getTimezoneOffset()

Returns the time difference between UTC time and local time, in minutes

Many people use moment.js to play with Date, I know it is not in your question but maybe you could find some usefull things
