  }
    private static void ShowPossibleUtcTimes(DateTime ambiguousTime, TimeZoneInfo timeZone)
    {
       // Determine if time is ambiguous in target time zone 
       if (! timeZone.IsAmbiguousTime(ambiguousTime))
       {
          Console.WriteLine("{0} is not ambiguous in time zone {1}.", 
                            ambiguousTime,
