Villeret Équation du Temps Marchante
The running equation of time shows the difference between mean solar time (the standard 24-hour day) and true solar time (based on the sun’s actual position), caused by Earth’s orbit and tilt. This rare complication tracks daily variation with astronomical precision and elegance.
