It is a curious thing - I think for the foreseeable future, we’d likely still track age via Earth years for the sake of avoiding this kind of thing. I wonder if/when we do colonize, how long would it take for the Martians to actually switch. How much would our cultures have drifted by that point?
And a related shower thought - until relatively recently (late 1960s), any definition we used to track time has been crazy localized to our planet, compared to other things in math and science where many of those concepts would still work the same elsewhere
