To return the “time” portion of the Date as a human-readable string, use the toTimeString() method in JavaScript. This method returns the time portion of a Date object in the human-readable form.
Example
You need to run the following code to return only the time portion of a Date −
<html> <head> <title>JavaScript toTimeString Method</title> </head> <body> <script> var dateobject = new Date(2018, 0, 1, 14, 39, 7); document.write( dateobject.toTimeString() ); </script> </body> </html>
