Syntax

dateObj.toTimeString()

Return value

A string representing the time portion of the given date in human readable form in English.

Description

Date instances refer to a specific point in time. Calling toString() will return the date formatted in a human readable form in 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.

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.

Examples

A basic usage of toTimeString()

var d = new Date(1993, 6, 28, 14, 39, 7);

console.log(d.toString());     // Wed Jul 28 1993 14:39:07 GMT-0600 (PDT)
console.log(d.toTimeString()); // 14:39:07 GMT-0600 (PDT)
