### Describe the bug As uncovered in https://github.com/apache/datafusion/pull/19460, `SELECT '2001-09-28'::date - '2001-08-12'::date` returns a Duration type whereas other systems return an int: https://www.postgresql.org/docs/current/functions-datetime.html https://duckdb.org/docs/stable/sql/data_types/interval#arithmetic-with-timestamps-dates-and-intervals https://dev.mysql.com/doc/refman/8.4/en/expressions.html#temporal-intervals Datafusion should adhere to common conventions for operation types unless there is a really good reason to deviate. IOW, this should work: query T SELECT arrow_typeof('2001-09-28'::date - '2001-08-12'::date) ---- Int64 ### To Reproduce See sql above ### Expected behavior date - date should return an int of the days difference between the two dates, not a duration. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
