I’m working on a network device right now that will have a clock display function for a project among friends. One of our plans is to incorrporate atomic time to ensure accuracy of the device. Getting to Atomic time is easier if you use NTP rather than try to parse it off of time.gov.
We haven’t got to that point of the project so I can’t guaruntee the code will be good or anything. But its something I know about at least. Anyways, I’m a hardware guy, what do I know.
