There are lots of situations where GNSS isn’t available, especially in broadcasting.
A live event in a convention center for example. You might have a truck outside with GNSS, but it’s blocked inside by the building.
I would rather not know the exact time than be spied on.
It's not for you. It's for a broadcasting team so all of the wireless camera feeds are properly synced.
In what situation would nanosecond accuracy be needed between cameras? Millisecond accuracy should be enough to get camera feeds in sync, even when looking at videos frame by frame.

Why do you think it could spy on you? Wi-Wi looks like has transmitters on 900MHz broadcasting the accurate time. It is like GPS but inside building.
