refactor: remove dead Date64 handling code from CSV writer Date64 is converted to Timestamp[ms] by Daft upon ingestion, so the Date64 match arm in transform_batch was dead code. This removes it and adds a comment explaining why Date64 is not handled separately. The test_write_csv_date64_with_timestamp_format test correctly uses timestamp_format (not date_format) because the data arrives as Timestamp[ms] by the time it reaches the CSV writer.

test: add more test coverage for date/timestamp CSV formatting Add additional tests to improve code coverage: - Test Date64 type formatting (uses timestamp_format since Daft converts to Timestamp[ms]) - Parametrized test for all timestamp time units (s, ms, us, ns) - Test default behavior when no custom format is provided This increases the test count from 33 to 39 tests for CSV writing.

fix: return error for invalid timezone strings in CSV timestamp formatting Instead of silently falling back to UTC when timezone parsing fails, return an error to alert users of invalid timezone strings (e.g., typos like "America/New_Yrok"). This is consistent with error handling in other parts of the codebase (e.g., src/daft-schema/src/time_unit.rs). - Add explicit error handling for timezone parsing failures - Add test case to verify error is raised for invalid timezones - Prevents silent data corruption from unintended UTC conversion Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

feat: add timezone support for timestamp formatting Add proper timezone handling when formatting timestamp columns with custom formats. Timezone-aware timestamps now preserve their timezone information instead of being converted to UTC. - Add chrono-tz dependency for timezone parsing - Extract and apply timezone from Arrow Timestamp type - Convert UTC timestamps to target timezone before formatting - Add test for timezone-aware timestamp formatting Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

feat: add custom date and timestamp formatting for CSV writes Add support for custom date and timestamp format strings when writing CSV files, allowing users to control how dates and timestamps are serialized. - Add date_format and timestamp_format parameters to DataFrame.write_csv() - Implement formatting using chrono's strftime format specifiers - Support all standard date/timestamp formats including ISO 8601 (%+) - Add comprehensive test coverage for various format scenarios Closes #3788 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
