--- Comment #3 from Aditya Keerthi <akeerthi at apple.com> ---
Ignoring the system preference in <input type=time> was an intentional anti-fingerprinting measure. As it stands, 12-hour and 24-hour time inputs have different sizing behavior that is discernible by the web page. For date/time inputs, our current behavior is designed to avoid exposing any additional information that is not already exposed through `navigator.language`.

The iOS implementation is much older (and separate) from macOS, and may need to be reconsidered to match privacy guarantees.
