Why the date values are different in Javascript

Question

All:

Quick question why the Javascript Date object built from a milsec number are different:

var ms = 1524862189829
new Date(1524862189829)
Fri Apr 27 2018 13:49:49 GMT-0700 (Pacific Daylight Time)
Date(1524862189829)
"Mon Apr 30 2018 15:29:44 GMT-0700 (Pacific Daylight Time)"

one shows Apr 27, but the other shows Apr 30, also the time are not same, which one is correct? This is the result from Chrome 65 console

Thanks

const ms = 1524862189829;
const d0 = new Date(ms);
const d1 = Date(ms);

const pd0 = document.getElementById('date0');
const pd1 = document.getElementById('date1');

pd0.innerText = d0.toString();
pd1.innerText = d1.toString();

<p id="date0">
</p>
<p id="date1">
</p>

@FelixKling Thanks, sometimes I just have no idea what key word I should search. But many thanks — Kuan, Apr 30 '18 at 22:43

Calling the Date() constructor without new just gives you the current date and time information as a string. It doesn't pay attention to the parameter you pass at all.
