    var now = DateTime.Now; // Current date/time
    var utcNow = now.ToUniversalTime(); // Converted utc time
    var otherTimezone = TimeZoneInfo.FindSystemTimeZoneById("ANY OTHER VALID TIMEZONE"); // Get other timezone
    var newTime = TimeZoneInfo.ConvertTimeFromUtc(utcNow, otherTimezone); // New Timezone

Answer 2

This should do the trick

DateTime localTime = TimeZoneInfo.ConvertTime(DateTime.UtcNow, TimeZoneInfo.Local);

Answer 3

You can use javascript:

 var visitortime = new Date();
    vat time = visitortime.getTimezoneOffset()/60;

After that you can save this value to any hidden control which is runat ="server".

Answer 4

Use TimeZoneInfo.ConvertTimeFromUtc. The example listed there is pretty self explanatory.

Answer 5

why not just

TimeZoneInfo.ConvertTimeBySystemTimeZoneId(DateTime.UtcNow, "AUS Eastern Standard Time");

and check get all available timezones

foreach (TimeZoneInfo tz in TimeZoneInfo.GetSystemTimeZones())
{
    Console.WriteLine(tz.Id);
}

Use the TimeZoneInfo Class to convert a local time to a time in an alternative timezone:

TimeZoneInfo est = TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time");
DateTime targetTime = TimeZoneInfo.ConvertTime(timeToConvert, est);
