The Date object is a data type built into the JavaScript language. Date objects are created with the new Date( ) as shown below.
Once a Date object is created, a number of methods allow you to operate on it. Most methods simply allow you to get and set the year, month, day, hour, minute, second, and millisecond fields of the object, using either local time or UTC (universal, or GMT) time.
The toJSON() function of the date object returns the simplified extended ISO format of the date.
Its Syntax is as follows
dateObj.toJSON();
<html>
<head>

</head>
<body>
<script type="text/javascript">
var dateObj = new Date('september 26, 89 12:4:25:96');
var jsonDate = dateObj.toJSON();
document.write("Current Date: "+jsonDate);
</script>
</body>
</html>
Current Date: 1989-09-26T06:34:25.096Z
If you do not pass parameters to the Date constructor this function returns the JSON containing the current time and date.
