using MessagePack;
using UnityEngine;
public class MainMenu : MonoBehaviour
{
  void Start()
  {
    for (int i = 0; i < 10; i++)
    {
      var b = MessagePackSerializer.Serialize(DateTime.Now);
      DateTime c = MessagePackSerializer.Deserialize<DateTime>(b);
      Debug.Log(c);
    }
  }
}

above script attached to maincamera of a 2d Scene.
