Goddard does not apply its computers to the task of projecting thousands of years into the future or past, as this would be irrelevant to the operational lifetime of satellites, which rarely exceeds a dozen years. Some people even say that solar time is more accurate than the clock, sundial is a important alternative to modern clock that gives time reading based on sunlight. Thus, another atheistic charge against the biblical narrative bites the dust, yet again.

These lengths will change slightly in a few years and significantly in thousands of years. Mean solar time is the hour angle of the mean Sun plus 12 hours. One could note the positions of the hands on the dial and make a reasonable guess about what the time of day was when the clock stopped running, but without knowing whether that time was A.M. or P.M., and without knowing the calendar date on which stoppage occurred, one could not possibly make any reasonable estimate about how long ago the clock stopped.

Then consider a second fictitious Sun travelling along the celestial equator at a constant speed and coinciding with the first fictitious Sun at the equinoxes. On the back is a time-line series. When the Sun crosses the equator at both equinoxes, the Sun's daily shift (relative to the background stars) is at an angle to the equator, so the projection of this shift onto the equator is less than its average for the year; when the Sun is farthest from the equator at both solstices, the Sun's shift in position from one day to the next is parallel to the equator, so the projection onto the equator of this shift is larger than the average for the year (see tropical year).
