Due to using nanoseconds as an intermediate state, the values for dates processed via "to_date" cannot be later than the year 2262. The Arrow datatype for Date32 and Date64 supports much larger values.

The statements in some areas in the code that the usage of nanoseconds is imposed by Arrow is simply wrong. The Date32 type stores the number of days since epoch. The Date64 type stores the milliseconds (NOT nanoseconds) since epoch. Both Date32 and Date64 can therefore massively exceed the year 2262.
