## What problem does this PR solve? Related Doris PR: https://github.com/apache/doris/pull/65446 The Doris change updates timestamp handling in FileScannerV2 and Parquet export, but the user-visible compatibility rules and migration options were not documented. Without this context, users can accidentally introduce an eight-hour shift while trying to compensate for legacy Parquet `INT96` writer behavior. ## What is changed? - Document that FileScannerV2 preserves raw Parquet `INT96` wall-clock fields by default, while Parquet `INT64` logical timestamps retain their standard semantics. - Document the Hive Catalog and external-file TVF compatibility property `hive.parquet.time-zone`, including validation, examples, scope, V1/V2 behavior, and `TIMESTAMPTZ` handling. - Explain why the property is Catalog-wide for Hive `INT96` columns mapped to `DATETIMEV2`, and recommend separating files written with different conventions. - Document round-half-up conversion from ORC nanoseconds to Doris microseconds, including second carry and conservative predicate pruning. - Correct the Parquet export property name to `enable_int96_timestamps` and describe its default, `INT96`/`INT64` result, and asynchronous Export persistence. - Keep the English and Simplified Chinese current documentation synchronized. Only current documentation is updated because apache/doris#65446 targets unmerged master behavior. Published 4.x, 3.x, 2.1, and Japanese documentation are intentionally unchanged. ## Validation - `git diff --check` — passed. - `yarn docs:features:changed` — passed with no findings. - `yarn docs:i18n-sync:changed` — English/Chinese current pages are synchronized; expected warnings remain for intentionally unchanged published versions and Japanese docs. - `yarn docs:links:changed` / `yarn docs:lint:changed` — no new link issues from this change; the commands report existing missing Hive Catalog anchors and existing repository-wide SEO/Markdown findings. - `yarn key-features:generate` - `./local_dev.sh build-all --versions current --skip-install --max-mem 8192` — generated English and Chinese current site output; the build reports existing repository-wide broken-link warnings. -- This is an automated message from the Apache Git Service.
