Does that mean you won't get to know the time unless you let them spy on your physical location too? That's what the diagram implies: https://www.gps.gov/sites/default/files/2025-06/CGSICMeeting...

GNSS time is still cooler because you can have extremely accurate time and a reading of your position without the broadcasting satellites knowing you're there.

I think it only needs the travel time of the signal, but it's not well explained.
