[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Ticklefish:
This is the status_bar.xml from my tablet. The tablet's still on Gingerbread so your code won't be very different.

<?xml version="1.0" encoding="utf-8"?>
<com.android.systemui.statusbar.StatusBarView android:background="@drawable/statusbar_background" android:orientation="vertical" android:focusable="true" android:descendantFocusability="afterDescendants"

Because the clock is on its own individual line, we can move it wherever we want to. This isn't possible on Froyo because the clock is called by the same process that calls the battery and signal images.

So we apply the code suggested by serajr (I have to be honest, it's a more elegant solution) and we end up with this:

<?xml version="1.0" encoding="utf-8"?>
<com.android.systemui.statusbar.StatusBarView android:background="@drawable/statusbar_background" android:orientation="vertical" android:focusable="true" android:descendantFocusability="afterDescendants"
xmlns:android="[URL]http://schemas.android.com/apk/res/android[/URL]">
<com.android.systemui.statusbar.Clock android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:paddingRight="6.0dip" android:textAppearance="@android:style/TextAppearance.StatusBar.Icon" android:singleLine="true" />
<LinearLayout android:orientation="horizontal" android:id="@id/icons" android:layout_width="fill_parent" android:layout_height="fill_parent">
<com.android.systemui.statusbar.IconMerger android:orientation="horizontal" android:id="@id/notificationIcons" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0" android:layout_alignParentLeft="true" android:paddingLeft="6.0dip" android:gravity="center_vertical" />
<LinearLayout android:orientation="horizontal" android:id="@id/statusIcons" android:layout_width="wrap_content" android:layout_height="fill_parent" android:gravity="center_vertical" android:layout_alignParentRight="true" android:paddingRight="6.0dip" />
</LinearLayout>
<LinearLayout android:orientation="horizontal" android:background="@drawable/statusbar_background" android:id="@id/ticker" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingLeft="6.0dip" android:animationCache="false">
<ImageSwitcher android:id="@id/tickerIcon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_marginRight="8.0dip">
<com.android.systemui.statusbar.AnimatedImageView android:layout_width="25.0dip" android:layout_height="25.0dip" />
<com.android.systemui.statusbar.AnimatedImageView android:layout_width="25.0dip" android:layout_height="25.0dip" />
</ImageSwitcher>
<com.android.systemui.statusbar.TickerView android:id="@id/tickerText" android:layout_width="0.0dip" android:layout_height="wrap_content" android:layout_weight="1.0" android:paddingRight="10.0dip" android:paddingTop="2.0dip">
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:textAppearance="@android:style/TextAppearance.StatusBar.Ticker" android:singleLine="true" />
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:textAppearance="@android:style/TextAppearance.StatusBar.Ticker" android:singleLine="true" />
</com.android.systemui.statusbar.TickerView>
</LinearLayout>
<com.android.systemui.statusbar.DateView android:background="@drawable/statusbar_background" android:id="@id/date" android:layout_width="wrap_content" android:layout_height="fill_parent" android:paddingLeft="6.0px" android:gravity="left|center" android:paddingRight="6.0px" android:textAppearance="@android:style/TextAppearance.StatusBar.Icon" android:singleLine="true" />
</com.android.systemui.statusbar.StatusBarView>

And that's it! See, once you know what all this is doing, you can easily apply it to practically any rom.
