work with dates before 1900 or timestamp before 1970

One approach: both type are string from storage, following a standard like [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601). The SQL execute engine parse it into the date and timestamp type that supports it, which are the internal structure do not counts to user

The issue describes storing dates before 1900 and timestamps before 1970 as ISO 8601 strings in storage, with the SQL engine parsing them into internal date/timestamp types. Research the storage layer and SQL execution engine code to understand current date/time handling. Look for existing date and timestamp type implementations and parsing logic. Determine what changes are needed to support the extended range and ensure consistent feature computation for machine learning.
