i am working with two js library to get browser timezone id and browser local time

    <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/jstimezonedetect/1.0.4/jstz.min.js"></script>
    <script src="Scripts/moment-timezone.min.js" type="text/javascript"></script>


<script type="text/javascript">
        $(document).ready(function () {
            var tz = jstz.determine(); // Determines the time zone of the browser client
            alert(tz.name());

            alert(moment.tz(tz.name()).format());
        });
    </script>

this below code return perfect timezone id

       var tz = jstz.determine(); // Determines the time zone of the browser client
        alert(tz.name());

but this code is not working alert(moment.tz(tz.name()).format()); not giving user local time.

Solution

My solution of this case (this is part of the page code):

function toLocalTime(time) {
	if (time <= 0)
		return '';
		
	var m = moment.tz(time, 'America/Chicago'); //CDT
	
	var tz = jstz.determine(); // Determines the time zone of the browser client
	
	m.tz(tz.name()); // Convert CDT to local time
	
	return m.format('HH:mm:ss');
}

<script src="js/jstz.min.js"></script>
<script src="js/moment.js"></script>
<script src="js/moment-timezone-with-data-2010-2020.js"></script>

...........

<script th:inline="javascript">document.write(toLocalTime(<<TIME IN MILLISECONDS HERE>>));</script>
