NSDate.ToDateTime() appears to be bugged

I've made some modifications to the ExtendedDatePicker in the Xamarin.Forms.Labs control lib to support Date and Time. I'm getting some curious behaviour with NSDate.ToDateTime(). My value changed handler is as follows:

private void HandleValueChanged (object sender, EventArgs e)
{
Console.WriteLine (this.picker.Date.ToString());
base.Element.Date = this.picker.Date.ToDateTime ();
Console.WriteLine (base.Element.Date.ToString());
}

and it produces the following output:

2014-10-22 14:31:35.427 Surveillance[6347:761500] 2014-10-18 03:00:00 +0000

2014-10-22 14:31:45.053 Surveillance[6347:761500] 10/18/2014 12:00:00 AM

Notice that the time portion of the datetime is incorrect.

Can anyone confirm that they have seen this behaviour before I log a bug in bugzilla? Or have I missed something fundamental here?
