last_changed_address_or_port is computed wrongly

Looking at the server_status fields for Najdorf I see something like:

published: 2024-06-16 23:00:00
last_changed_address_or_port: 2024-06-16 23:00:00

and

published: 2024-06-17 00:00:00
last_changed_address_or_port: 2024-06-17 00:00:00

However, the Onionoo documentation says

UTC timestamp (YYYY-MM-DD hh:mm:ss) when this relay last stopped announcing an IPv4 or IPv6 address or TCP port where it previously accepted onion-routing or directory connections. This timestamp can serve as indicator whether this relay would be a suitable fallback directory.
