Your URL suggests you are in the admin area. Have you decorated your controller with the area attribute? Try removing the area attribute and see if the styles get rendered properly.

[Area(AreaNames.Admin)]

Looks like you are on the admin area and you are using the layout used in public portal. You have to use either

Layout = "_ConfigurePlugin";

Layout = "_AdminLayout";

as the layout in the admin section.

You can create an editor template to achieve this.
Create an editor template named TimeNullable.cshtml inside the editortemplate directory where the other templates are located. Use this code

@model DateTime?
<input id="@Html.IdForModel()" name="@Html.NameForModel()" value="@(Model > DateTime.MinValue || Model.HasValue ? Model.Value.ToShortDateString() : null)" />
<script>
    $(document).ready(function () {
        $("#@Html.IdForModel()").kendoTimePicker({
            dateInput: true
        });
    });
</script>

and decorate your property name with

       [UIHint("TimeNullable")]
        public DateTime? StartTime{ get; set; }

This should be it. I have not tried it in 3.9 but it should be similar to this
