Example

The following example illustrates the use of the GetUtcOffset(DateTime) method with different time zones and with date values that have different Kind property values.


using System;/*from  ww w . j av a  2s. c  o m*/

   public class TimeOffsets
   {
      public static void Main()
      {
         TimeOffsets timeoff = new TimeOffsets();
         TimeZoneInfo cst = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time");

         timeoff.ShowOffset(new DateTime(2006, 6, 12, 11, 0, 0), TimeZoneInfo.Local);
         timeoff.ShowOffset(DateTime.UtcNow, TimeZoneInfo.Local);
         timeoff.ShowOffset(new DateTime(2006, 6, 12, 11, 0, 0), TimeZoneInfo.Utc);
         timeoff.ShowOffset(DateTime.Now, TimeZoneInfo.Utc);
         timeoff.ShowOffset(new DateTime(2006, 6, 12, 11, 0, 0), cst);
         timeoff.ShowOffset(new DateTime(2007, 11, 14, 00, 00, 00, DateTimeKind.Local), cst);
      }

      private void ShowOffset(DateTime time, TimeZoneInfo timeZone)
      { 
         TimeSpan offset;
         offset = timeZone.GetUtcOffset(time);
         Console.WriteLine(offset);                                             
      }
   }

The code above generates the following result.
