When using:

Date.toLocaleTimeString()

is there any way to have it display 01:42:35 PM instead of 1:42:35 PM?

I have tried adding in this:

Date.toLocaleTimeString(navigator.language, {hour: '2-digit', minute:'2-digit', second: '2-digit'})

but it still only produces a single digit hour (unless it is after 10).

• There is no Date.toLocaleTimeString, there is Date.prototype.toLocaleTimeString though. It's part of the internationalisation API and not supported by all browsers in use. – RobG Commented Aug 28, 2016 at 22:50

If my reading is right, according to the relevant spec, it appears this is intentional.

• Else if f is "2-digit", then
  • Let fv be FormatNumber(nf2, v).
  • If the length property of fv is greater than 2, let fv be the substring of fv containing the last two characters.

I can't understand why it would be specified that way, but there it is. If you want to do zero-padding, it seems you'll just need to prepend it yourself.

It worked in this way for me

var datelocal = new Date(2016, 01, 01, 1, 1, 1).toLocaleTimeString(navigator.language, {
hour: '2-digit',
minute: '2-digit',
second: '2-digit'
});

i'm also attached a plunker.

NOTE: you have to provide new Date() instead of passing date parameters to Date method to get the current date.

Instead of relying on Date.prototype.toLocaleTimeString or similar functions to get the right format in such situations, I tend to use Moment.js in my JavaScript project. Moment.js is a JavaScript library which is specifically designed to parse, validate, manipulate and display dates. To get a string for the time in the format you described, you could use:

var s = moment().format('hh:mm:ss A');
console.log(s);

This uses the current date. If you want to use another date, you can do so, too:

var s = moment(new Date(2016, 8, 19, 1, 10)).format('hh:mm:ss A');
console.log(s);

It saves you the hassle of doing your own zero-padding and other similar stuff.

The correct answer is to use "2-digit" in hour

const options = {hour: '2-digit', minute: '2-digit', second: '2-digit'};

        function ut() {
            let d = new Date();
            document.getElementById('time').innerHTML = d.toLocaleTimeString('de-DE', options);
        }
        window.setInterval(ut, 1000);

#time {
            font-size: 40px;
            text-align: center;
            white-space: nowrap;
            color: black
        }

<div id="time"></div>
