IANA time zone database. • This functionality requires several new types to be added to the library: • tzdb • tzdb_list • time_zone • zoned_time • time_zone_link • ambiguous_local_time • nonexistent_local_time zones; • vector links; • vector leap_seconds; • And has member functions: • const time_zone* locate_zone(string_view tz_name) co nst; • const time_zone* current_zone() for time zone data We had a few options... • Ship the entire IANA time zone database with the library The IANA time zone database is huge (1.25MB) – we would have some very unhappy customers if their
