How to get the time zone besides to time stamp

Hello All,

Hope you are doing good!!

Here i have written a code for getting the browser time zone(comparing with server time zone),

By that i need to print the time zone also beside to time stamp..

Here i am adding the code and screenshot..

public partial class WebForm1 : System.Web.UI.Page
{
public static DateTime getClientTime(string date, object ClientTimeZoneoffset)
{
string s1 = "";
s1 = ClientTimeZoneoffset.ToString().Substring(0, ClientTimeZoneoffset.ToString().IndexOf("#"));
if (s1 != null)
{
string Temp = s1.ToString().Trim();
if (!Temp.Contains("+") && !Temp.Contains("-"))
{
Temp = Temp.Insert(0, "+");
}
//Retrieve all system time zones available into a collection
ReadOnlyCollection timeZones = TimeZoneInfo.GetSystemTimeZones();
DateTime startTime = DateTime.Parse(date);
DateTime _now = DateTime.Parse(date);
foreach (TimeZoneInfo timeZoneInfo in timeZones)
{
string str = Regex.Match(ClientTimeZoneoffset.ToString(), @"\(([^)]*)\)").Groups[1].Value;
if (timeZoneInfo.ToString().Contains(Temp) && timeZoneInfo.Id.ToString().Contains(str))
{
TimeZoneInfo tst = TimeZoneInfo.FindSystemTimeZoneById(timeZoneInfo.Id);
_now = TimeZoneInfo.ConvertTime(startTime, TimeZoneInfo.Utc, tst);
break;
}
}
return _now;
}
else
return DateTime.Parse(date);
}
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack == true)
{
if (String.IsNullOrEmpty(HiddenFieldClientTime.Value) == false)
{
string Temp = HiddenFieldClientTime.Value;
// call the method to convert the utc now time to client time
TextBox1.Text = getClientTime(DateTime.UtcNow.ToString(), Temp).ToString();
}
}
}
}
}

function calculate_time_zone() {

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));

alert('your time zone is ' + jan1);
}
