Gerald, are seriously suggesting that, for Mars, the hour, minute and second

You are even more delusional than I thought! Why would this possible be an
advantage in any way?

In fact, *Robert Zubrin* suggested exactly the same thing.

While the SI second will obviously be useful on Mars as everywhere else for
defining the frequencies of radio waves, and so on and so forth, people living
on Mars would want to have a way to refer to *the time of day*, and cutting the
day, nearly as long as the day on Earth, into pieces following the same,
familiar plan used on Earth is the simplest thing to do.

Mars wris****ches have existed for years. They are used by the operators of
Mars landers who need to start their shift times earlier every day. Since
the first of these were slowed down Earth time watches they implicitly use
Martian seconds.

For human settlers on Mars I like the “witching hour” method of Vernor
Vinge from Across Realtime where the standard Earth time is used with an
extra period tagged onto the end of the day. But this would have problems
with geographically (areographically) separated settlements.




The simplest concepts are the easiest to get wrong. Later not earlier.
