### SUMMARY Python 3.12 deprecated `datetime.utcnow()` and `datetime.utcfromtimestamp()`. This sweeps all production occurrences under `superset/` (8 files, ~29 call sites) and replaces them with **behavior-preserving** equivalents: ``` datetime.utcnow() → datetime.now(timezone.utc).replace(tzinfo=None) datetime.utcfromtimestamp(x) → datetime.fromtimestamp(x, timezone.utc).replace(tzinfo=None) ``` The values stay **naive UTC**, exactly as before. This is a deliberate choice — and the key difference from the earlier #37538, which switched to *aware* datetimes. Superset stores naive UTC datetimes in the metadata DB, so switching to aware values would raise naive/aware comparison errors (e.g. the `Log.dttm` prune query on PostgreSQL — see the existing comment in `superset/commands/logs/prune.py`) and would change `isoformat()`/cache-key output. Keeping the values naive makes this a pure no-op refactor that just removes the deprecation. `superset/security/session_invalidation.py` already uses `datetime.now(timezone.utc)` and is intentionally left unchanged. ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF N/A — no functional or UI change. ### TESTING INSTRUCTIONS No behavior change; the produced datetime values are identical to before (naive UTC), so existing tests cover these paths. `pre-commit` (ruff, ruff-format, mypy, pylint) passes on all changed files. ### ADDITIONAL INFORMATION - [ ] Has associated issue: - [ ] Required feature flags: - [ ] Changes UI - [ ] Includes DB Migration (follow approval process in [SIP-59](https://github.com/apache/superset/issues/13351)) - [ ] Introduces new feature or API - [ ] Removes existing feature or API Scope is limited to production code under `superset/` to keep the diff easy to verify as a no-op. Test files under `tests/` still use the deprecated calls and can be migrated in a focused follow-up. 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
