WebAPI allow only single date format

Inside my WebAPI I have method that allows user to register to my page.

[AllowAnonymous]
[Route("create")]
[HttpPost]
public async Task<IHttpActionResult> CreateAccount(MyModel newAccount)
{
}

My model has DateTime field that is filled with date when request is made.
Everything works fine when user sends for example 1990-02-07 but for 07.02.1980 I get incorrect value inside my model - date nad month switch values.
I know I can create custom JsonConverter as shown here, but can I do it globally?

Inside Startup.cs I have:

config.MapHttpAttributeRoutes();

config.Formatters.Remove(config.Formatters.XmlFormatter);
var jsonFormatter = config.Formatters.OfType<JsonMediaTypeFormatter>().First();
jsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
jsonFormatter.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
jsonFormatter.SerializerSettings.DateFormatString = "yyyy-MM-dd";
jsonFormatter.SerializerSettings.DateParseHandling = DateParseHandling.DateTime;

but still I can do request with invalid date format.

I would like to globally allow single format for date and time.
I would like to allow yyyy-MM-dd (1990-02-07) and yyyy-MM-dd hh:mm:ss (2016-07-28 11:56:00) and return badrequest or invalid request when other format is specified without even processing data.

You can create your own Json media formatter for date and register it for DateTime type.. Here is the example code for media formatter 

public class JsonDateFormatter : JsonMediaTypeFormatter
{
    public override System.Threading.Tasks.Task<Object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger, CancellationToken cancellationToken)
    {
        //Do date formatting here
    }

    public override bool CanReadType(Type type)
    {
        if (type == typeof(DateTime))
            return true;
        return false;
    }
}

and here is how you can register it in Startup.cs

config.Formatters.Add(new JsonDateFormatter());
