The system of equal hours,minutes and seconds is anchored in the creation of the 24 hour day which in turn is anchored to the noon cycle (day/night). The mean value relies on the mathematical principle that when different amounts are combined and divided equally they give an average or mean value, in this case what would be different hours,minutes and seconds for each noon cycle is reduced to an average or constant value.

The deficient observers launches into impressive values with multiples decimal places with first identifying where the 24 hour day comes from, what references are used and how it relates timekeeping to geometry/geography via longitude and Latitude.

To create a geostationary satellite system for Mars requires the planet have its own timekeeping system constructed around the planet's Lat/Long system and although the latter is easy enough to construct, the Martian hour is not.

Considering the hapless go out of their way to promote the idea that the Earth has more rotations than 24 hour days (day/night cycles) as their system demands it, there is every reason to put our planet's timekeeping evolution in historical and technical context.
