PS: missed your second post about DateChoose controls, this is something that you would have to program your self as Roberts widget is set up to use input fields, but it is a good place to start

One of my 2012 Dev Summit presentations included code and a widget for crime mapping exactly what you are talking about. It is not a mod for the eSearch it is a completely new widget, but you could glean all the basics from it. The biggest thing is SQL date ranges are a nightmare but setting a time extent works beautifully.
