MVC Handle Null Date from View to Controller

I have an MVC View which has an optional <input /> for a Date.
The Model (Generated from a DB) has the DateTime field as Not Null

If the user decides to leave the field blank, the View will get passed back to the Controller, which will then validate everything and save it away to a DB.

The issue comes in where the null value being passed back is either 1900-01-01 12:00:00 PM OR DateTime.Min, depending on the server (Right now two different Dev machines).

The Min Date needed in the DB is 1900-01-01 12:00:00 PM, so to circumvent this, I have the following check:

person.PaidDate = person.PaidDate == DateTime.MinValue || person.PaidDate == DateTime.Parse("1900-01-01 12:00:00 PM") ? DateTime.Parse("1900/01/01 12:00:00") : person.PaidDate;

Is this the best, or most correct way of checking for a supposedly null date being brought back from the Controller ?

You could add a model binder.

public class DateModelBinder : IModelBinder
{
    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var dateTime = bindingContext.Model as DateTime?;
        var result = dateTime.GetValueOrDefault() == DateTime.MinValue 
            ? DateTime.Parse(SqlDateTime.MinValue.ToString()) 
            : dateTime.Value;
        return result;
    }
}

Register it in Global asax.

ModelBinders.Binders.Add(typeof(DateTime), new DateModelBinder());
