the following test case works on windows but fails on mono. Note that this used
to work as of a couple weeks ago so it seems to have been broken recently.

   class monofail6
   {
      static int Main(string[] args)
      {

         DateTime dtm = new DateTime(2010, 7, 7, 10, 10, 10, 10,
DateTimeKind.Local);
         LocalDateTime localDateTime = new LocalDateTime(dtm);

         BinaryFormatter bf = new BinaryFormatter();
         MemoryStream ms = new MemoryStream();
         bf.Serialize(ms, localDateTime);
         ms.Position = 0;

         LocalDateTime dateTime2 = (LocalDateTime)bf.Deserialize(ms);

         Console.WriteLine("Original Date:" + dtm.ToString());
         Console.WriteLine("Current  Date:" + dateTime2);

         if (dtm != dateTime2.DateTime)
            throw new Exception("dates are not equal!!");

         Console.WriteLine("Worked!!");
         return 0;
      }

      [Serializable]
      public struct LocalDateTime : ISerializable
      {
         private DateTime m_localDateTime;
         public LocalDateTime(DateTime dt)
         {
            m_localDateTime = dt;
         }

         private LocalDateTime(SerializationInfo info, StreamingContext
context)
         {
            m_localDateTime =
DateTime.FromBinary(info.GetInt64("LocalDateTime"));
         }

         public DateTime DateTime
         {
            get { return m_localDateTime; }
            set { m_localDateTime = value; }
         }

         void ISerializable.GetObjectData(SerializationInfo info,
StreamingContext context)
         {
            info.AddValue("LocalDateTime", m_localDateTime.ToBinary());
         }

         public override string ToString()
         {
            return m_localDateTime.ToString();
         }
      }

   }
