@amackif yes, agreed.
And I would also consider chrono as "broken/unfitting/lacking". The jiff docs explain why much better than I could.
I think as it comes to date and time handling, the reason isn't lack of interest but the huge complexity of time zones, daylight saving time shifts, and leap periods.
I admire the teams behind RFC 9557, Temporal as well as BurntSushi for taking this on.
