Equation of time sundial
WebAn equation clock is a mechanical clock which includes a mechanism that simulates the equation of time, so that the user can read or calculate solar time, as would be shown by a sundial. The first accurate clocks, controlled by pendulums, were patented by Christiaan Huyghens in 1657. WebA westward shift causes the sundial to be ahead of the clock. Since the main effect of this oscillation concerns time, it is called the equation of time, using the word "equation" in a somewhat archaic sense meaning …

WebNo, they mean the maximum difference between local time and the time on your sundial will be 15 minutes. Since the sun changes its apparent position over the year, the time difference between the sundial and local time changes too. It's not a cumulative effect, like a clock winding down. – gargoylezoo.

WebThe equation of time specifies the difference between time calculated using a sundial or sextant--which is known as solar time --and time obtained from an accurate clock--which is known as mean solar time.
