ASP.NET MVC datetime culture issue when passing value back to controller

Question

How can i tell my controller/model what kind of culture it should expect for parsing a datetime?

I was using some of this post to implement jquery d

You can create a Binder extension to handle the date in the culture format.

This is a sample I wrote to handle the same problem with Decimal type, hope you get the idea

 public class DecimalModelBinder : IModelBinder
 {
   public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
   {
     ValueProviderResult valueResult = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
     ModelState modelState = new ModelState { Value = valueResult };
     object actualValue = null;
     try
     {
       actualValue = Convert.ToDecimal(valueResult.AttemptedValue, CultureInfo.CurrentCulture);
     }
     catch (FormatException e)
     {
       modelState.Errors.Add(e);
     }

     bindingContext.ModelState.Add(bindingContext.ModelName, modelState);
     return actualValue;
  }
}

Update

To use it simply declare the binder in Global.asax like this

protected void Application_Start()
{
  AreaRegistration.RegisterAllAreas();
  RegisterGlobalFilters(GlobalFilters.Filters);
  RegisterRoutes(RouteTable.Routes);

  //HERE you tell the framework how to handle decimal values
  ModelBinders.Binders.Add(typeof(decimal), new DecimalModelBinder());

  DependencyResolver.SetResolver(new ETAutofacDependencyResolver());
}

Then when the modelbinder has to do some work, it will know automatically what to do. For example, this is an action with a model containing some properties of type decimal. I simply do nothing

[HttpPost]
public ActionResult Edit(int id, MyViewModel viewModel)
{
  if (ModelState.IsValid)
  {
    try
    {
      var model = new MyDomainModelEntity();
      model.DecimalValue = viewModel.DecimalValue;
      repository.Save(model);
      return RedirectToAction("Index");
    }
    catch (RulesException ex)
    {
      ex.CopyTo(ModelState);
    }
    catch
    {
      ModelState.AddModelError("", "My generic error message");
    }
  }
  return View(model);
}
