Abstract: The mean sun is an artificial
construction in astronomy which is used to define civil
time. It has the property that local mean time, dependent on
the geographical position on the earth's surface, behaves
regularly, which is not true for the (true) local time, which
depends on the real sun. We present a functional equation which
reflects this regularity property of the mean sun and show that the
solution to this equation essentially is the mean sun. Moreover we
discuss the problem of satellite TV.
