During a normal day, the intensity of sunlight, as a vector, is measured. By calculating variation of angle between sun’s ray and surface of the earth, angular velocity of the Earth’s rotation at different time intervals is determined. This angular velocity is not unchanging and traces back to the variations in intensity of light emanating from the Sun.
