Update: ECMAScript 2017 (ECMA-262)

padStart has been added to pad the beginning of a string with another string, where the first value is the length it should be and the second value being what to pad it with.

For example:

let d = new Date()

let h = `${d.getHours()}`.padStart(2, '0')

let m = `${d.getMinutes()}`.padStart(2, '0')

let s = `${d.getSeconds()}`.padStart(2, '0')



let displayDate = h + : + m + : + s

// Possible Output: 09:01:34

Pre-ECMAScript 2017

As far as I know, there's not. And I do this all the time for converting dates to the XML dateTime format.

It's also important to note that those methods you list return a number, not a string.

You can, of course, add these yourself by modifying Date.prototype.

Date.prototype.getHoursTwoDigits = function()

{

    var retval = this.getHours();

    if (retval < 10)

    {

        return (0 + retval.toString());

    }

    else

    {

        return retval.toString();

    }

}



var date = new Date();

date.getHoursTwoDigits();
