Option to reduce the empty space to the sides of the clock (and possibly the Start button as well)

The feature to reduce the gap between the notification area icons was pretty useful. I would like to see a similar one for the clock, which still leaves a lot of unused space to its left and right. And maybe one for the Start button as well. It doesn't need to cover as much space as it does since most people move the mouse cursor to the bottom left corner of the screen when they intend to click it (Fitt's law). Ideally it would positioned more to the left and there would be less of a gap between it and the elements to the right (whether they're a toolbar's icons, pinned items, or running programs).
