Abstract
A mechanism for determining whether the sun is visible at a diurnal solar event and for mechanically triggering actions based upon the sun being visible during the diurnal solar event is disclosed. The mechanisms of the invention can perform these operations without intervention or supervision for long periods of time. Certain embodiments have been applied to provide a diurnal solar event trigger based upon sidereal noon for a clock providing accurate timing for 10,000 years without intervention or supervision.
