If I have an html control in my page. 

```
<input type="text" id="dateFrom" runat="server" ClientIDMode="Static"/>

```

On a button click, I save the value of input `dateFrom` to a Sitecore item's field with type "`DateTime`"

**CodeBehind:** 

```
item["Visible From"] = dateFrom.Value;

```

I am using Jquery to show a calendar when user clicks inside the input `dateFrom`

```
$(function () {
        $("#dateFrom").datepicker();
    });

```

After saving the item, the result I see in the "Content Editor" is:

The correct date is some how not saving. I also tried with `<asp:TextBox` 
instead of `<input type="text"` but still same result.
