16 days agoNot true. My 2015 car uses gps satellites to determine its clock. In 2019 there was a gps week number rollover due to a 10-bit counter rolling over. My car hasn’t had the correct time since and the manufacturer doesn’t distribute update CDs for it. I can set the clock manually and even change the settings to not auto update, but it resets every time I turn off the car.
So while yes the satellites just count seconds, it’s interpreted by other devices and the differences will confuse them.


Irrelevant, you said the receivers didn’t care, and they definitely need updates to read the GPS satellites’ output correctly.
