SHDate.toLocaleTimeString()

The toLocaleTimeString() method returns a string with a language-sensitive representation of the time portion of the date. The newer locales and options arguments let applications specify the language formatting conventions to use. These arguments can also customize the behavior of the function.

More dated implementations ignore the locales and options arguments. In these circumstances, the form of the string returned is entirely implementation-dependent.

Try it

Syntax

toLocaleTimeString();
toLocaleTimeString(locales);
toLocaleTimeString(locales, options);

Parameters

The locales and options arguments customize the behavior of the function and let applications specify which language formatting conventions should be used. In older implementations that ignore the locales and options arguments, the locales and the form of the string returned will be entirely implementation-dependent.

See the Intl.DateTimeFormat() constructor for details on these parameters and how to use them.

The default value for each date-time component property is undefined, but if the hour, minute, second properties are all undefined, then hour, minute, and second are assumed to be “numeric”.

Return value

A string representing the time portion of the given Date instance according to language-specific conventions.

Performance

When formatting large numbers of dates, it is better to create an Intl.DateTimeFormat object and use the function provided by its format property.

Examples

Using toLocaleTimeString() Basic use of this method without specifying a locale returns a formatted string in the default locale and with default options.

var date = new SHDate(SHDate.UTC(1402, 11, 12, 3, 0, 0));

// toLocaleTimeString() without arguments depends on the implementation,
// the default locale, and the default time zone
console.log(date.toLocaleTimeString());
// → "7:00:00 PM" if run in en-US locale with time zone Asia/Tehran

Using locales
This example shows some of the variations in localized time formats. In order to get the format of the language used in the user interface of your application, make sure to specify that language (and possibly some fallback languages) using the locales argument:

var date = new SHDate(SHDate.UTC(1402, 11, 20, 3, 0, 0));

// formats below assume the local time zone of the locale;
// Asia/Tehran for the IR

// US English uses 12-hour time with AM/PM
console.log(date.toLocaleTimeString('en-US'));
// → "7:00:00 PM"

// British English uses 24-hour time without AM/PM
console.log(date.toLocaleTimeString('fa-IR'));
// → "06:30:00"

// Korean uses 12-hour time with AM/PM
console.log(date.toLocaleTimeString('ko-KR'));
// → "오후 12:00:00"

// Arabic in most Arabic speaking countries uses real Arabic digits
console.log(date.toLocaleTimeString('ar-EG'));
// → "٧:٠٠:٠٠ م"

// when requesting a language that may not be supported, such as
// Balinese, include a fallback language, in this case Indonesian
console.log(date.toLocaleTimeString(['ban', 'id']));
// → "11.00.00"

Using options
The results provided by toLocaleTimeString() can be customized using the options argument:

var date = new SHDate(SHDate.UTC(1402, 11, 20, 3, 0, 0));

// an application may want to use UTC and make that visible
var options = { timeZone: 'UTC', timeZoneName: 'short' };
console.log(date.toLocaleTimeString('en-US', options));
// → "3:00:00 AM GMT"

// sometimes even the US needs 24-hour time
console.log(date.toLocaleTimeString('en-US', { hour12: false }));
// → "19:00:00"

// show only hours and minutes, use options with the default locale - use an empty array
console.log(date.toLocaleTimeString([], { hour: '2-digit', minute: '2-digit' }));
// → "20:01"
