+        This property returns a `datetime.tzinfo` object if the Timestamp
+        is timezone-aware. If the Timestamp has no timezone, it returns `None`.
+        If the Timestamp is in UTC or a fixed-offset timezone,
+        it returns `datetime.timezone`. If the Timestamp uses an
+        IANA timezone (e.g., "America/New_York"), it returns `zoneinfo.ZoneInfo`.
