We follow a systematic approach to the process of learning, examining and certifying. Traditionally, there are three types of time reckoning based on astronomical observations: apparent solar time and mean solar time (discussed in this article), and sidereal time, which is based on the apparent motions of stars other than the Sun.[1]. The concept described here would be like giving someone a non-functioning clock and asking him to determine how much time had elapsed since the clock had stopped running. Flammarion also calculated the exact inclination of the gnomon to get a retro-gradation of 10 (according to 2 Kings 20:11), namely 18 north-latitude. Cambridge researchers announced Monday that they have pinpointed the date of the biblical account of Joshua stopping the sun which they claim is the day of the oldest eclipse ever recorded to October 30, 1207 BCE, exactly 3,224 years ago.

For an azimuthal (horizontal, vertical, or diagonal) sun dial, the angle is expressed as a number of degrees (e.g., 0 = 360).

What this sundial exactly looked like was initially unclear. (The primary means of reckoning the passage of time in Joshua's era was by observing the apparent movement of celestial bodies through the sky relative to the observer. Because the sun was difficult to observe directly due to its large size in the sky, mean solar time was determined as a fixed ratio of time as observed by the stars, which used point-like observations. A sundial was included as part of the Mars lander mission and is shown in "Astronomy Picture of the Day" for 28 April 1999.
