The equation of time is the difference between apparent solar time and mean solar time. At any given instant, this difference will be the same for every observer. The equation of time can be found in tables (for example, The Astronomical Almanac) or estimated with formulas given below.
Apparent (or true) solar time can be obtained for example by measurement of the current position (hour angle) of the Sun, or indicated (with limited accuracy) by a sundial. Mean solar time, for the same place, would be the time indicated by a steady clock set so that over the year its differences from apparent solar time average to zero (with zero net gain or loss over the year).
The word "equation" is here used in a somewhat archaic sense, meaning "correction". Prior to the mid-17th Century, when pendulum-controlled mechanical clocks were invented, sundials were the only reliable timepieces, and were generally considered to tell the right time. The right time was essentially defined as that which was shown by a sundial. When good clocks were introduced, they usually did not agree with sundials, so the equation of time was used to "correct" their readings to obtain sundial time. Some clocks, called equation clocks, included an internal mechanism to perform this correction. Later, as clocks became the dominant good timepieces, uncorrected clock time was accepted as being accurate. The readings of sundials, when they were used, were then, and often still are, corrected with the equation of time, used in the reverse direction from previously, to obtain clock time. Many sundials therefore have tables or graphs of the equation of time engraved on them to allow the user to make this correction.

This clip shows how the equation of time differs from normal time by about 15 minutes per day plus or minus throughout the year on the main dial. It also shows how the differential drive outboard wheel dips and rises throughout the year controlled by the equation kidney cam. Of course this action is one year compressed into only a few seconds. Also under normal operation the equation hand will precede or fall behind the regular clock dial's minute hand by these amounts through out the year. The differentials within this subsystem under normal operation will maintain these two hands is a relative position to each other. -

Astro skeleton equation of time demonstration
Astro skeleton equation of time demonstration
This clip shows how the equation of time differs from normal time by about 15 minutes per day plus or minus throughout the year on the main dial. It also shows how the differential drive outboard wheel dips and rises throughout the year controlled by the equation kidney cam. Of course this action is one year compressed into only a few seconds. Also under normal operation the equation hand will precede or fall behind the regular clock dial's minute hand by these amounts through out the year. The differentials within this subsystem under normal operation will maintain these two hands is a relative position to each other.- published: 14 Dec 2014
