In ASP.NET MVC 4, when you have a DateTime property in your model, with a data annotation of DataType.Time, it still generates a "data-val-date" attribute in the resulting html.

I reported an issue related to this for Internet Explorer where it was closed as by design.

The problem I'm having is that MVC is generating the data-val-date="The field Time must be a date." attribute for DateTimes with no DataType-attribute which causes Internet Explorer to fail clientside validation for big endian datetimes: 2012-12-14 15:22. It requires the first separator to be a / instead: 2012/12-14 15:22

So even when using a custom template for the editor and my own validation for jQuery Internet Explorer runs some other validation which fails. This is not an issue on other tested browsers (Chrome, Opera, Firefox).

Same problem with jquery datepicker and DateTime?. Tryed to force DateType.Text, but unsuccessfull. Found work around with removing data-val-date attribute by javascript. This is really annoying. BTW, in MVC3 I didn't see this problem.

Have you released the updated MVC runtime?

I was running into the same problem. After some googling i found the solution.
I have changed my datetime field to a timespan field.

    public TimeSpan Time{ get; set; }

EF will create a Time (time(7), not null) column in the related model table.

Hopefully this will solve your problems aswell.

I'm seeing the same thing, for this data model:

        [DisplayName("Ship Time")]
        public DateTime? StartDateTime { get; set; }

The validation is telling me:

The field Ship Time must be a date.

Thank you,

Yes, I see this problem, too. Is there a workaround?

I have a DateTime field in my data model and I CANNOT USE the Edit screens generated by MVC4. When I edit a record it displays the correct Date+time, but I cannot save the unchanged record! For my field named TransactionTimestampClient I get validation error "The field TransactionTimestampClient must be a date."

here is my data model
        [Display(Name = "TransactionTimestampClient")]
        public DateTime TransactionTimestampClient { get; set; }

I'm sorry for the delay, I only got a notification for the last update, not the previous one...

What do you actually mean with "give us a video"?

It's quite easy to reproduce the behavior by simply creating a controller (and views) derived from this model class:
public class MyModel
    [Required, DataType.Time]
    public DateTime Time
and then look at the generated html for the "Create" view.
