the solar time

Solar time is the time measured according to the position of the Sun in the sky. It is 12 o'clock solar time (noon) when the Sun is highest in the sky. North of the tropics, the Sun is then due south, and south of the tropics it is due north then. You can measure the solar time with a well-adjusted sundial. Solar time is usually not equal to the official clock time. In the Netherlands and Belgium, solar time is about 40 minutes behind official clock time in winter, and about one hour and 40 minutes behind in summer.
