remove the local timezone from a date in javascript?

I believe d.toDateString() will output the format you’re looking for.

var d = new Date();
d.setTime(1432851021000);
d.toDateString(); // outputs to "Thu May 28 2015"
d.toGMTString(); //outputs to "Thu, 28 May 2015 22:10:21 GMT"

Or even d.toLocaleString()
“5/28/2015, 6:10:21 PM”

There are lots of methods available to Date()
