 Temporal data types are implemented by the `neo4j.time` module.
 It provides a set of types compliant with ISO-8601 and Cypher, which are similar to those found in Python's native `datetime` module.
 To convert between driver and native types, use the methods `.from_native()` and `.to_native()` (does not apply to `Duration`).
+This conversion is lossy, as the driver's types support nanosecond precision, while Python's native types do not.
 
-Sub-second values are measured to nanosecond precision and the types are mostly compatible with link:https://pypi.org/project/pytz/[pytz].
-Some timezones (e.g., `pytz.utc`) work exclusively with the built-in `datetime.datetime`.
+[NOTE]
+The driver's temporal types are designed to be used with link:https://pypi.org/project/pytz/[pytz].
+Other `datetime.tzinfo` implementations (e.g., `datetime.timezone`, `zoneinfo`, `dateutil.tz`) are not supported and are unlikely to work well.
