The creation of a timekeeping system for Mars will include weeks, months and years/leap years that mirror the Earth's timekeeping structure in principle but adapted to different weeks and months within a framework that is presently calculated as 687 Earth days ( Earth day/night cycles).

Timekeeping is anchored to noon which also carries along sunrise/sunset as a function of the day/night cycle. The Earth has two distinct day/night cycles - the 24 hour day/night cycle and the Polar day/night cycle.

A space age race of people shouldn't find the experience of separate day/night cycles difficult as their combination generates the seasons which are arbitrary divisions of the annual cycle into 4 components. The ancient Celtic year is more accurate as it breaks the year into a light half and dark half thereby represents the rotation behind the annual day/night cycle as being a rotation parallel to the orbital plane.

The foundation of a distinct timekeeping system for Mars along with a Lat/Long system can be accomplished in a straightforward and neat way compared to the thousands of years that went into timekeeping evolution on Earth, at least the one we inherit today.

Such a development doesn't require actors who are lost or behave like some politicians who say nothing while appearing to say something as the two nuisances in this thread have shown.
