The average length of a Martian sidereal day is 24 h 37 m 22.663 s (88,642.663 seconds based on SI units), and the length of its solar day is 24 h 39 m 35.244 s (88,775.244 seconds). 3 The corresponding values for Earth are currently 23 h 56 m 4.0916 s and 24 h 00 m 00.002 s, respectively… (Wikipedia)
By Caulfield’s rule, minutes and seconds on Mars would be longer than earth minutes and seconds. This would not matter if there were no communication between the planets, but is a problem when there is.
I suppose that if we can trust AIs to handle little details like that it would not cause strain, except for those who physically travel between worlds. But for the time being, Mars will use earth seconds, minutes and hours…
Interestingly, Kim Stanley Robinson in his Mars trilogy (Red Mars, Green Mars, Blue Mars) had colonists use a 24 hour earth day, which left them with that 39+ minutes that more or less fell between “days”
