Hi gang, and no I'm not using Object Dock Plus as a hat, as someone suggested. 
I've have used a Zoomer and Tabbed dock now for a while but never really saw the need for a third dock untill recently. I've been putting Theme Manager Suites together based upon WindowBlinds Themes. There are always folks from the community making additional skins to go with them with usually one exception a clock. You can find lots of DX clock widgets or objects to use but they don't always fit in.
My fix, add an additional dock to the desktop, in my case a second zoomer, put a clock docklett on it and get rid of the other dockletts. Now go apply the Themed background to the dock. Now it matches the theme. Move the dock around to where you want it. Work great, even get the day and date on mouse over. There are lots of clock dockletts in the Object Dock Library to download.
I would do it with a Weather Widget too except in Win 7 the Weather Widget doesn't show up in the add a docklett function. Someone should look at that. 
Yeah I know you folks knew this a long time ago, I'm so slow.
