The Equation of Time and the Analemma, by Kieron Taylor
An article by Brian Tung containing a link to a C program using a more accurate formula than most (particularly at high inclinations and eccentricities). The program can calculate solar declination, Equation of Time, or Analemma.

帶有顯示均時差輔助錶盤的時鐘。 那不勒斯的但丁廣場（1853）。
動畫顯示了一年內的均時差和日行跡路徑。
1812年由赫斯特父子，用圓形刻度表示均時差的修正。這件作品現在正在德比博物館與藝術畫廊展出。
均時差（紅色實線）及其兩個分別繪製的主要分量，一部分是由於黃道的傾角（淡紫色虛線），另一部分是由於太陽沿黃道的視速度變化，這是由於地球軌道的離心率（深藍色虛線和點線）。
當地正午的太陽和行星（黃道帶為紅色，太陽和水星為黃色，金星為白色，火星為紅色，木星為黃色與紅色斑點，土星為白色與光環）。
地心觀察者看到的天球和太陽的橢圓軌道，看起來垂直於黃道，顯示計算軍時差所必需的6個角度（M, λp, α, ν, λ, E）。為清楚起見，圖不按比例縮放。
