toTimeString() method returns the time portion of a Date object in human readable form in American English.
Date instances refer to a specific point in time. Calling toString() will return the date formatted in a human readable form in American English. In SpiderMonkey, this consists of the date portion (day, month, and year) followed by the time portion (hours, minutes, seconds, and time zone). Sometimes it is desirable to obtain a string of the time portion; such a thing can be accomplished with the
toTimeString() method is especially useful because compliant engines implementing ECMA-262 may differ in the string obtained from toString() for Date objects, as the format is implementation-dependent; simple string slicing approaches may not produce consistent results across multiple engines.
var d = new Date(1993, 6, 28, 14, 39, 7); console.log(d.toString()); // logs Wed Jul 28 1993 14:39:07 GMT-0600 (PDT) console.log(d.toTimeString()); // logs 14:39:07 GMT-0600 (PDT)
