That is simply not true.
Time is a system for describing the continuous passage of events from past to present to future. Time can be measured in large increments such as years, months, and days, as well as in small increments such as hours and seconds. The passage of time is measured in three principle ways: rotational time, dynamic time, and atomic time.
Rotational time has as its basic unit the mean solar day, which is the average time it takes the Earth to complete one rotation about its axis.
Dynamic time relies not only on the orbital movements of the Earth, but on the movements of the moon and/or planets as well. The first dynamic time scale was Ephemeris Time, proposed in 1896 and modified in 1960. Ephemeris Time is based on the orbit of the moon around the Earth. The motion of the moon is determined by observing its position with respect to the stars. Given that the Earth's rotation exhibits slight variations in...
Atomic time is a third way to measure time. This method, using an atomic clock, is based on the extremely regular oscillations that occur within atoms. In 1967, the atomic second (the length of time in which 9,192,631,770 vibrations are emitted by a hot cesium atom) was adopted as the basic unit of time. Atomic clocks are now used as international time standards
The sun is not our only source of measurment for time. and even if it was, which it is not, as i said, it still debunks your entire theory, of whatever it is you were trying to say,
