The Equation of Time....

 

The equation of time measures the difference between the civil time, and the real solar time. This difference, due to the Earth’s elliptical orbit, varies between -16 and +16 seconds daily which makes a maximum annual difference of +14 and -16 minutes. The 24-hour day is the civil time which represents a compromise of the variation.


Hence the +/- 15 scale at 4 o'clock.

Hope this explains the function, my friend
