Python 3.12 deprecated datetime.utcnow() and datetime.utcfromtimestamp(). This sweeps all production occurrences under superset/ (8 files) and replaces them with behavior-preserving equivalents that keep the existing naive-UTC semantics: datetime.utcnow() -> datetime.now(timezone.utc).replace(tzinfo=None) datetime.utcfromtimestamp(x) -> datetime.fromtimestamp(x, timezone.utc).replace(tzinfo=None) Keeping the values naive (rather than switching to aware datetimes) avoids naive/aware comparison errors against timestamps already stored naive in the metadata DB (e.g. the Log.dttm prune query on PostgreSQL) and keeps isoformat()/cache-key output byte-identical. This is the key difference from the earlier #37538, which switched to aware datetimes. superset/security/session_invalidation.py already uses now(timezone.utc) and is left unchanged. Test files still use the deprecated calls and can be migrated in a focused follow-up. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
