I just love playing with my phone settings, when I discovered this advanced settings on my device.

Follow procedure accordingly to try it out;

1. Swipe down your notification bar, Tap and hold on gear settings icon.
 
You will receive a congratulations message

2. Scroll down to system UI tuner.



3. Open and you will see some advanced settings 


4. In my case I open status bar to set seconds timer. 
Note: There are other settings there, just be careful with changes you made.
