what's expected behavior for casting timestamp with timezone to timestamp without time zone? e.g. if the timestamp with timezone is `1970-01-01T08:00:00+08:00` (note that the timestamp underline is 0), what's the casted result? `1970-01-01T08:00:00` (underline timestamp as 28800000000000) or `1970-01-01T00:00:00` (underline timestamp as 0)? i recommend that listing these ambiguous cases and your proposed behavior so we could discuss btw i tested it on pyarrow, it simply changes the datatype but not change the underline timestamp (`1970-01-01T08:00:00+08:00` becomes `1970-01-01T00:00:00` -- This is an automated message from the Apache Git Service.
