Hi @ZhengLin-Li , I think you're confusing arrow's parser with DF's parser. The job of a parser in a programming language is to validate the syntax and build an AST. TIMESTAMP '2023-12-05T21:58:10.45ZZTOP' is syntactically correct, as TIMESTAMP 'x' and TIMESTAMP '' (empty string). This is a semantics issue which, in typical programming languages, is check by the semantic analysis step. In the case of SQL, and as stated in the issue's expected behavior, this should be handled by the optimizer; or worst case scenario by the query executor (think of interpreted languages that catch semantics error during execution). -- This is an automated message from the Apache Git Service.
