Temporal.Duration: https://tc39.es/proposal-temporal/docs/#Temporal-Duration

IIRC Python datetime objects initially lacked timezone support and a timezone database.

datetime.MINYEAR and the "can't represent datetimes before the Unix epoch, or before 0001-01-01" problem.

E.g. Astropy supports astronomical year numbering and year zero.

"When was the Osireon built?"

If the answer is greater than 2025 years ago (is a BCE date by the Gregorian calendar) or Year Zero, the answer cannot be represented unless the datetime or temporal.Duration object supports negative years or different year zeroes.
