For calendars, could define that if year = max_year + 1, then that is considered infinity? Similar with negative infinity. This could possibly work because the max year is defined to be 32767 due to the use of a short for year, but we store our year in an int due to having to be compatible with R. Since all calendar types have a year field, 32767 + 1 could be infinity?
After figuring out how the storage would work, then it would be a matter of fixing the print method and adding special support everywhere to ensure propagation is working as expected. Not easy!
For time points, could follow the duckdb approach of using
INT64_MAX/MINas special infinity values https://github.com/duckdb/duckdb/blob/8edeaf41a6a683d9df84d609a4f7660ef5f8d8d9/src/include/duckdb/common/types/timestamp.hpp#L79-L88For calendars, could define that if
