Yes. My test is as follows: For testing the z values I used to the GPX files from #6, and for testing the datetime I took any GPX file and tried to animate it using "temporal properties" (the built-in time manager), see https://docs.qgis.org/3.34/en/docs/user_manual/working_with_vector/vector_properties.html#temporal-properties
