The getTime method returns the quantity of milliseconds passed since January 1st 1970 until the point in time stored in a Date object. The value returned by this method is an integer number.
Syntax
myDate.getTime()
With myDate being an object based on the Date object.
Instead of being instantiated from a class, in JavaScript objects are created by replicating other objects. This paradigm is called Prototype-based programming.
Example

<script type="text/javascript">
var currentDate = new Date();
document.write("It has been " + currentDate.getTime() + " milliseconds since January 1st 1970.");
</script>
var currentDate = new Date();
document.write("It has been " + currentDate.getTime() + " milliseconds since January 1st 1970.");
</script>
