Javascript adding Timezone in my current script

i have this code on my script to show ticking clock

<script type="text/javascript">
    function showTime() {
        var date = new Date(),
            time = new Date(Date.UTC(
                date.getFullYear(),
                date.getMonth(),
                date.getDate(),
                date.getHours(),
                date.getMinutes(),
                date.getSeconds()
            ));

        document.getElementById('time').innerHTML = time.toLocaleTimeString();
    }

    setInterval(showTime, 1000);

</script>

Anyone know how to change the timezone to a specific timezone like "Asia/Jakarta"
Thanks before!

>Solution :

for info : — list of TZ

const timeDisplay = document.getElementById('time');


timeDisplay.textContent = new Date().toLocaleTimeString('ID','Asia/Jakarta')
 

<p id="time"></p>
