This is the only part of your code that we care about:

In green is the code for the left side of your statusbar, that's the notification icons.

In blue is the code for the right side of your statusbar, that's the clock, battery icons, signal icons, etc.

I assume this is Cyanogenmod?

The methods from the first post still apply. To use the Best Method of centering the clock, you need to make your code look like this:

Now your statusbar has a centred clock and it's easy to move certain icons around. For example, if you want the statusicons on the left side of the statusbar,you can now easily cut and paste the line to the statusbarleftside layout.
