Example
HTML Online Editor
<!DOCTYPE html>
<html>
<body>
<p>Click the button to display the timedifference between UTC and local time.</p>
<button onclick="myFunction()">Display Time Difference</button>
<p id="point"></p>
<script>
// verifying getTimezoneOffset().
function myFunction(){
// local date
var d = new Date();
var m = d.getFullYear();
var n = d.getMonth();
var o = d.getDate();
var p = d.getHours();
var q = d.getMinutes();
var r = d.getSeconds();
var s = d.getMilliseconds();
//UTC date
var utcDate = Date.UTC(m, n, o, p, q, r, s);
//convert milliseconds to minutes
d = d / (60 * 1000);
utcDate = utcDate / (60 * 1000);
// result
var result = d - utcDate;
document.getElementById("point").innerHTML = result;
}
</script>
</body>
</html>
