> Given a parquet file with a int96 date 9999-12-31 on it (which does not fit in an i64 ns) is read as a "wrapped", resulting in the date 1816-03-29 05:56:08.066277376.
> Spark seems to discard the nanoseconds and only read int96 to micros, which gives them a 1000x of dates (which happens to cover the 9999, but not others). There is a long discussion over this issue here: https://github.com/apache/arrow-rs/issues/982 including a MWE for pyarrow.
