In the 2008 Q2 (and now in the Q3 as well) versions of the suite, I've witnessed some strange behaviour with the TimeView.
Basically I've got a form which opens in a RadWindow containing a RadDateTimePicker and a RadTimePicker on one line in the form. The TimeView for both pickers is relatively wide and fills the entire width of the RadWindow, so for the RadTimePicker I had used style="margin-left: -300px;" to offset it back enough to be visible. This worked until Q2.
Now, what I'm witnessing (in IE7), is a disabled scrollbar at the bottom of the TimeView for both of the pickers, which is the width of the TimeView (in this case, 520px). The left-most part of this scrollbar always lines up with the left-side of the picker's textbox - meaning that the "margin-left: -300px;" does not affect the position of that scrollbar. In my case, this causes a vertical scrollbar to appear in the RadWindow. On top of that, though, the rest of the TimeView does get offset by the -300px but the part that is offset is not visible on the page.
Here's a screenshot:
