    That information is not sent to the server, so there is not trivial way to do it. One option would be to look up the IP in a Geolocation Database. http://www.ip2location.com/ is one.

    You can also do a ajax postback using the javascript Date.getTimezoneOffset().

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

    and store this in the session or with the user data.

    If you have troubles showing time on the client side then you can do the following I wrote an extension to DateTime class that does 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've added a javascript file and let momentjs handle the conversion on the client side

    $(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');
    });

  • It will have to be done on the Javascript side, and post that value in a hidden field back to the server. Look into the Date.getTimezoneOffset().
