I am sure the ISIS branch of astronomy would find 'sidereal vs solar' convictions acceptable however the integrity of the Lat/Long system and the 24 hour system is as intimate as it is inviolate - the 'average' 24 hour day and its creation substitutes for 'constant' rotation at a rate of 15 degrees per hour.

Before the accumulative inspiration/genius of humanity and its long endeavor to create a system of timekeeping as principles and engineering, people should not behave like brutes even though they presently do. The mongrel system which is currently applied to Mars will not serve geostationary satellites for the planet and especially not a system like GPS which refers longitude coordinates to timekeeping.

The equable hour,minute and second will be as individual to Mars as the maximum equatorial distance across 15 degrees of longitude. Clearly none of you are up to the necessary principles which will eventually go into an individual calendar framework with a leap day/rotation correction.
