javascript date equality confusion

Question

I have two dates who are equal when new Date is used but their getTime()'s are different.

Here are both dates:

1) Wed Nov 25 2015 08:00:00 GMT-0500 (EST) 
2) Wed Nov 25 2015 08:00:00 GMT-0500 (EST)

Their getTime()'s are:

1) 1448456400924 
2) 1448456400000

Off by a small amount, What is the cause of this? I've used both setSeconds(0) and setMinutes(0) on one date, the logs are what you see.

Juhana thanks thats probably it. That was it upvoted your comment. Thanks again. — shell, Nov 28 '15 at 00:55

Javascript Dates have millisecond precision: The getTime() method returns the number of milliseconds between midnight of January 1, 1970 and the specified date.

var date = new Date().setMilliseconds(0)

The last 3 digits are the issue, and the above code would correct 1448456400924 to 1448456400000 as an example.
