## Which issue does this PR close? Closes #5716. ## Rationale for this change Spark accepts explicit positive years such as `+7528`, but Comet returns NULL. Malformed signs also bypass ANSI errors. ## What changes are included in this PR? Accept either year sign in the shared timestamp patterns and remove the duplicated `+` handling from the TIMESTAMP and TIMESTAMP_NTZ parsers. Restore positive-year fuzz coverage. ## How are these changes tested? Rust and Parquet-backed SQL regressions cover Legacy, TRY, and ANSI casts, signed dates, timezone suffixes, and malformed signs. All 33 native string-cast tests and 14 targeted Spark 4.1.3 tests pass, including the 10,000-input fuzz test. -- This is an automated message from the Apache Git Service.
