为什么我不能从给定的字符串创建一个新的Date（）？

Question

I'm using moment.js to find a time in different timestamp. I wrote a simple javascript:

$(function () {
    var timestamp = 1443556318; //GMT Tue, 29 Sep 2015 19:51:58 GMT
    var today2 = moment.unix(timestamp).tz('America/New_York').toString();
        today = new Date(today2);
        alert(today2);
        alert(today);

        var hh = today.getHours();
        alert(hh); //why it shows me 21 instead of 15?   
});

and seems like this line today = new Date(today2); does not work properly. Can you help me with that?

It doesn't work because, you use the following constructor

new Date(dateString);

where the

String value representing a date. The string should be in a format recognized by the Date.parse() method (IETF-compliant RFC 2822 timestamps and also a version of ISO8601).

If you want to all the possible constructors, please have a look here .
