How to convert unix timestamp to JavaScript date object (consider time zone)
===

    var date = new Date(1257397200000​);
    document.write(date);
    ​
Ran the code above I got `Wed Nov 04 2009 23:00:00 GMT-0600 (Central Standard Time)`

I am looking for a way to create date object based on different time zone, say for that time stamp I want to obtain date object like `Thursday, November 5th 2009, 00:00:00 (GMT -5)`. 

Note that the dates are different according to above two time zones. I am in CST, is that why the created object is generated using CST? 

Thank you.
