Example

The following example illustrates the difference between the ToUniversalTime and TimeZoneInfo.ConvertTimeToUtc(DateTime, TimeZoneInfo) methods on a Windows XP system in the U.S. Pacific Time zone.

//from  ww w.jav  a2 s  .  c o  m
using System;

public class Example
{
   public static void Main()
   {
      DateTime date1 = new DateTime(2014, 3, 21, 2, 0, 0);

      Console.WriteLine(date1.ToUniversalTime());
      Console.WriteLine(TimeZoneInfo.ConvertTimeToUtc(date1));

      TimeZoneInfo tz = TimeZoneInfo.FindSystemTimeZoneById("Pacific Standard Time");  
      Console.WriteLine(TimeZoneInfo.ConvertTimeToUtc(date1, tz));     
   }
}

The code above generates the following result.
