MVC ModelState validation failing for null value

If I have the following model:

public class Model
{
    public int ModelID { get; set; }
    public string Title { get; set; }
    public DateTime Created { get; set; }
}

And the following controller method:

public ActionResult Create(Model model)
{
    if (ModelState.IsValid)
    {
        model.Created = DateTime.Now;

        // Save to DB
    }
}

In the view the Created field is hidden as I want this to populate with the timestamp of when the Create controller method is called. This fails ModelState validation due to the model.Created property being null.

I don't want to make the model.Created property Nullable but I need to somehow specify that this field isn't required in the view. Can someone please advise how to accomplish this?

You'll want to exclude the Created property from binding using the [Bind] attribute, as follows:

public ActionResult Create([Bind(Exclude = "Created")] Model model)
{
    ....
}

It is also recommended for security reasons, as you don't want your client to set Created value for you.
