Sorry, misread.
I see the form is dirty at debug time but are any of the elements (controls) dirty as well? If so you at least know which control is causing the problem. If none are dirty then I'd suspect the timepicker. If you can't prevent the problem then, if you can identify when it happens, you can use $setPristine() on the form to clear it.
