Description
The Equation of Time complication allows the viewer to understand the variation between Solar time, as measured by exact position of the sun and Mean Solar time, the position averaged over a year. This differential could be as much as +- 14 to 16 minutes per day depending on the time of year, due to the slight elliptical motion of the earths rotation around the sun.
The outer ring is marked with months and days and when aligned at the current date, a revised minute dial shows the compensated time at that moment.
