Mars Needs Leap Days Too

I'd be more interested to see if a more generalised PlanetDate module could be written. Perhaps outside of Earth we could do away with months and just stick to days (based on rotations, assuming the planet rotates) and years, with leap days added in between? And if the planet doesn't rotate, just count by hours and years (with hours having a logical separator at 10 or 100)?

I think any interplanetary civilization will be practically forced to use a planet-agnostic time system - a true UTC

That'd be TCB--https://en.wikipedia.org/wiki/Barycentric_Coordinate_Time

But we'd need a different standard if we colonized planets outside our solar system.
