Every time I handle datetimes in software I'm newly shocked by how annoying it is to get right

It's a really interesting problem to think about timekeeping in a relativistic world.
A different way of thinking: suppose there's two events A (on Earth) & B (on Mars) which appear simultaneous in the Earth or Mars rest frame. When Earth & Mars at furthest distance those events will appear ~ 1 microsecond apart in the rocket frame, ie, thousands of clock cycles!

Even worse, thanks to relativity of simultaneity, which of those two events is observed to comes first depends on the rocket's direction of travel. (I think. My memory of my special relativity classes is now more than a decade rusty)
-
though in some ways I often think that this problem would act as a kind of date-time accelerationism. Interplanetary time keeping is *so* bad, that it might actually force us to do it properly, ditch all the silly calendaring stuff, and use the right abstractions for time.

I cannot wait for the 3 point jira-ticket: show minutes until event as a function of the position of the spaceship
