I'm running into an issue on a clients production server where the month & day is being swapped on a view model property when saving an entity. For example if I were to select April 9th 2012 (04/09/2012) within the datepicker the date is being saved as September 4th 2012 (09/04/2012).

The same controller actions are working correctly on local development / test server and I'm unsure of what to look at next?

The property in the viewmodel:

[DisplayName("Date")]
[Required]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yy}")]
[DataType(DataType.Date)]
public DateTime StartDate { get; set; }

The helper within the relevant view:

@Html.EditorFor(model => model.StartDate)

The jquery ui datepicker:

$('#StartDate').datepicker({ dateFormat: 'mm/dd/yy' });

The stripped down version of the controller:

public ActionResult Create(BulletinBoardViewModel bulletin)
{
    var model = AutoMapper.Mapper.Map<BulletinBoardViewModel, BulletinBoard>(bulletin);
    _repository.Save(model);

    return RedirectToAction("Index");
}

The headers of the related post:

StartDate:04/09/2012

听起来客户端的服务器设置为英国英语而不是美国。这是一个常见的 CultureInfo 问题。无论哪种方式，当对象被持久化时，日期值应该仍然是正确的。由于 UI 文化选择，它只是以不同的方式显示。

你能识别出这是一个实际问题的特定代码，而不仅仅是一个明显的问题吗？

此外，它实际上并没有被保存为 9 月 4 日。你就是这么读的。尝试挑选，例如，12 月 31 日。保存实体后，您可能会看到 2012 年 12 月 31 日。服务器只是以 dd/MM/yyyy 格式显示日期。
