Ah, CyanogenMod...is it bad I can tell that just by looking at this code? I have spent far too long studying xml lately...

Anyway..

This is your normal code, which you shared in your post:

The simplest way to center the clock is to do this:

<?xml version="1.0" encoding="utf-8"?>

If you have lots of notifications, the icons will overlap the clock. There is a way to fix that but it's a bit more complicated.
