As a Java Dev, the thing that frightens me most about colonizing Mars is that we have to rewrite the Date class...

But I hope we will way less number of timezones to handle

It really is scary. Imagine you're traveling, how will the time zone as you're going there? The flight would take about a month I think according to latest info from SpaceX. Do you keep using earth days? Will we have 2 dates? What if things need to sync? Fuck.

It would probably end up using ship time I.e. The time zone used by the country that owns the vehicle and stick to earth units days, hours, etc.

You know it has already been done, yeah?

Is LocalDate not going to work?

'Yoda-Time' will be usable across the galaxy...

Try Frink, runs on JVM: https://frinklang.org//...

Why does it need to be rewritten and not extended?
