Get client computer timezone in asp.net mvc

Question

How to get timezone id (ex: Central Standard Time) of a client machine in asp.net mvc?

Answer 1

This needs to be done on the Javascript side and send this value to the hidden field back to the server. Take a look at Date.getTimezoneOffset () .

Answer 2

This information is not sent to the server, so there is no easy way to do this. One option is to find the IP address in the geolocation database. http://www.ip2location.com/ is one.

ajax javascript Date.getTimezoneOffset().

$.get('/User/SetTimeZone' + Date.getTimezoneOffset());

.

Answer 3

If you have problems indicating the time on the client side, you can do the following I wrote an extension for the DateTime class that does the conversion for me

public static MvcHtmlString ToClientTime(this DateTime dateTime){
   var builder = new TagBuilder("span");
   builder.MergeAttribute("data-utc-time",dateTime.ToString());
   builder.SetInnerText(string.Format("{0} (UTC)", dateTime.ToString()));
   return new MvcHtmlString(builder.ToString());
}

then I added a javascript file and let momentjs handle the client side conversion

$(document).ready(function() {
  $("[data-utc-time]").text(function () {
    var utcTime = $(this).attr("data-utc-time");
    return moment.utc(utcTime, 'DD.MM.YYYY HH:mm').local().format('DD.MM.YYYY HH:mm');
});
