One of our STEM interns recently observed that there are inexpensive clocks that sync via radio to standard time services. This begged a question about why every computer would not have a radio module to receive time. Our senior staff did not have a good answer or if time from such a radio module would be supported by the operating system.
When I was a student, such questions would have earned me extra homework assignments. We now have only PC directed relationships with interns so we don't assign any extra homework for curiosity. Can anyone help with the answers?
Because we connect directly to a known time server, which are all synced with the atomic clocks of places like the NIST, or Greenwich, etc. This is what NTP or chrony is for.
Why add a radio receiver when you're already online, and can connect to one from the US federal gov't?
