I do not understand. As a function of TAI, UTC is neither continuous
nor monotone increasing in the mathematical sense.

If, however, this Martian second is actually defined as a particular
multiple of the SI second, then the use of leap seconds on Mars would
ultimately be necessary to account for any future changes in the
length of the Martian day.
I see Steve Allen has already supplied a thorough answer. Interested
individuals might also scrounge through the list archives (http://

before. In fact, Demetrios Matsakis speculated on solar system wide

I don't have an envelope large enough, but there are various issues
to consider. The Hurtling Moons of Barsoom are much smaller than our
own and should have a negligible tidal breaking effect. (See http://
