Our model has public DateTime date { get; set; }.  In our view, our dates are being stored in the JSON date format.  We're then trying to save updates to the date   
var someObject = {};
someObject.date = JSONDate;
$.post("Controller/SaveAction", someObject, callback);  
and our controller has public JsonResult SaveAction(ModelType model) { ... } but this code breaks because it is unable to convert the JSON date to a c# DateTime object.
How can I convert the JSON date to something that the post will controller will be able to correctly read into a C# DateTime object?
