How to show the time zone

Jan 28 2020 6:12 PM
Hello Members,
 
Hope you are doing good!!
 
We  trying to get the browser time zone, We are good with that..
Need to show time zone also(Example: IST,CST,PST) 
 
Here I am adding the code below...
 
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Time Zone</title>
<script type="text/javascript">
var minutes;
function calculate_time_zone() {
debugger;
var rightNow = new Date();
var jan1 = new Date(rightNow.getFullYear(), 0, 1, 0, 0, 0, 0); // jan 1st
var june1 = new Date(rightNow.getFullYear(), 6, 1, 0, 0, 0, 0); // june 1st
var temp = jan1.toGMTString();
var jan2 = new Date(temp.substring(0, temp.lastIndexOf(" ") - 1));
temp = june1.toGMTString();
var june2 = new Date(temp.substring(0, temp.lastIndexOf(" ") - 1));
var std_time_offset = (jan1 - jan2) / (1000 * 60 * 60);
var daylight_time_offset = (june1 - june2) / (1000 * 60 * 60);
var dst;
if (std_time_offset == daylight_time_offset) {
dst = "0";
}
else
{
var hemisphere = std_time_offset - daylight_time_offset;
if (hemisphere >= 0)
std_time_offset = daylight_time_offset;
dst = "1";
}
var i;
// Here set the value of hidden field to the ClientTimeZone.
minutes = convert(std_time_offset);
TimeField = document.getElementById("HiddenFieldClientTime");
debugger;
TimeField.value = minutes + '#' + ' ' + jan1;
alert('your time zone is ' + jan1);
}
// This function is to convert the timezoneoffset to Standard format
function convert(value) {
var hours = parseInt(value);
value -= parseInt(value);
value *= 60;
var mins = parseInt(value);
value -= parseInt(value);
value *= 60;
var secs = parseInt(value);
var display_hours = hours;
// handle GMT case (00:00)
if (hours == 0) {
display_hours = "00";
} else if (hours > 0) {
// add a plus sign and perhaps an extra 0
display_hours = (hours < 10) ? "+0" + hours : "+" + hours;
} else {
// add an extra 0 if needed
display_hours = (hours > -10) ? "-0" + Math.abs(hours) : hours;
}
mins = (mins < 10) ? "0" + mins : mins;
return display_hours + ":" + mins;
}
// Adding the funtion to onload event of document object
onload = calculate_time_zone;
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:HiddenField ID="HiddenFieldClientTime" runat="server" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
