Center Clock Mod and its Color

1. Decompile SystemUI.apk

2. Search for Systemui/res/layout/tw_status_bar.xml

3. Delete all these lines

<LinearLayout android:orientation="horizontal" android:id="@id/icons" android:paddingLeft="0.0dip" android:paddingRight="2.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent">
<LinearLayout android:orientation="horizontal" android:id="@id/left_icons" android:paddingLeft="4.0dip" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0">
<TextView android:textSize="15.0dip" android:gravity="center_vertical" android:id="@id/carrierLabel" android:visibility="gone" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" />
<ImageView android:id="@id/operatorLogoIcon" android:visibility="gone" android:layout_width="wrap_content" android:layout_height="fill_parent" android:src="@drawable/tw_stat_notify_operator_logo" />
<ImageView android:id="@id/doNotDisturbIcon" android:visibility="gone" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/tw_dnd" android:alpha="0.7" android:scaleX="0.85" android:scaleY="0.85" />
<com.android.systemui.statusbar.StatusBarIconView android:id="@id/moreIcon" android:visibility="gone" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="fill_parent" android:src="@drawable/stat_notify_more" />
<com.android.systemui.statusbar.phone.IconMerger android:gravity="center_vertical" android:orientation="horizontal" android:id="@id/notificationIcons" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentLeft="true" />
</LinearLayout>
<LinearLayout android:orientation="horizontal" android:id="@id/right_icons" android:paddingRight="4.0dip" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentRight="true">
<LinearLayout android:gravity="center_vertical" android:orientation="horizontal" android:id="@id/statusIcons" android:layout_width="wrap_content" android:layout_height="fill_parent" />
<LinearLayout android:gravity="center" android:orientation="horizontal" android:id="@id/signal_battery_cluster" android:paddingLeft="2.0dip" android:layout_width="wrap_content" android:layout_height="fill_parent">
<include android:id="@id/signal_cluster" android:layout_width="wrap_content" android:layout_height="wrap_content" layout="@layout/tw_signal_cluster_view" />
<TextView android:textSize="12.0dip" android:textColor="#ffa6a6a6" android:layout_gravity="center" android:id="@id/battery_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/status_bar_network_name_separator" />
<ImageView android:gravity="center" android:id="@id/battery" android:layout_width="wrap_content" android:layout_height="wrap_content" />
</LinearLayout>
<com.android.systemui.statusbar.policy.Clock android:textSize="@dimen/status_bar_clock_text_size" android:textColor="#ff959595" android:ellipsize="none" android:gravity="left|center" android:id="@id/clock" android:paddingLeft="3.0dip" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" android:includeFontPadding="false" />
</LinearLayout>

4. Substitute with the following and save.

<LinearLayout android:orientation="horizontal" android:id="@id/icons" android:paddingLeft="1.0dip" android:paddingRight="1.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent">
<LinearLayout android:orientation="horizontal" android:id="@id/left_icons" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0">
<TextView android:textSize="15.0dip" android:gravity="center_vertical" android:id="@id/carrierLabel" android:visibility="gone" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" />
<ImageView android:id="@id/operatorLogoIcon" android:visibility="gone" android:layout_width="wrap_content" android:layout_height="fill_parent" android:src="@drawable/tw_stat_notify_operator_logo" />
<ImageView android:id="@id/doNotDisturbIcon" android:visibility="gone" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/tw_dnd" android:alpha="0.7" android:scaleX="0.85" android:scaleY="0.85" />
<com.android.systemui.statusbar.StatusBarIconView android:id="@id/moreIcon" android:visibility="gone" android:layout_width="@dimen/status_bar_icon_size" android:layout_height="fill_parent" android:src="@drawable/stat_notify_more" />
<com.android.systemui.statusbar.phone.IconMerger android:gravity="center_vertical" android:orientation="horizontal" android:id="@id/notificationIcons" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_alignParentLeft="true" />
</LinearLayout>
<LinearLayout android:gravity="center" android:orientation="horizontal" android:id="@id/clock" android:layout_width="wrap_content" android:layout_height="fill_parent">
<com.android.systemui.statusbar.policy.Clock android:textSize="@dimen/status_bar_clock_text_size" android:textColor="[COLOR="Red"]#ffffffff[/COLOR]" android:gravity="center" android:layout_width="wrap_content" android:layout_height="fill_parent" android:singleLine="true" />
</LinearLayout>
<LinearLayout android:gravity="right|center" android:orientation="horizontal" android:id="@id/right_icons" android:layout_width="0.0dip" android:layout_height="fill_parent" android:layout_weight="1.0" android:layout_alignParentRight="true">
<LinearLayout android:gravity="right|center" android:orientation="horizontal" android:id="@id/statusIcons" android:layout_width="wrap_content" android:layout_height="fill_parent" />
<LinearLayout android:gravity="right|center" android:orientation="horizontal" android:id="@id/signal_battery_cluster" android:paddingLeft="2.0dip" android:layout_width="wrap_content" android:layout_height="fill_parent">
<include android:id="@id/signal_cluster" android:layout_width="wrap_content" android:layout_height="wrap_content" layout="@layout/tw_signal_cluster_view" />
<TextView android:textSize="12.0dip" android:textColor="#ffa6a6a6" android:layout_gravity="center" android:id="@id/battery_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/status_bar_network_name_separator" />
<ImageView android:gravity="center" android:id="@id/battery" android:layout_width="wrap_content" android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>

5. look on the red part in above lines - this is the color you can set for clock (it is set to white in this case)

6. recompile SystemUI.apk and push to your device

ff defines level of transparency, so do not change it as the clock text won't be clear enough to read.

Put your favorite color code for the XXXXXX value.
