You have to use apkmanager to decompile your SystemUI.apk file, as well as set up apkmanager to use the frameworks-res.apk as a resource. Once you decompile it, you need to move the clock above the LinearLayout of the rest of the status bar in the xml file. Then you recompile it and use adb in recovery to push it to your phone.
Another problem. The only thing I have trouble with in your build is that I can only get the Clock and Reception, etc... to show up if something pops up. Like Statics Opted in, Preparing SD Card. Otherwise the bar stays black. Is there a fix?
