Arduino Uno based NTP Server


Arduino in router client list     Accurate Time: Ham radio digital modes require accurate computer time. On the other hand, appliance computer hardware clocks do nottypically maintain accurate time in the absence of periodic correction. Clock adjustments are generally accomplished automatically via scheduled updates from an Internet time service. But what if Internet connectivity is not readily available, or is prohibitively expensive, such as when operating from a remote area, perhaps a wilderness park? In such a situation it would be convenient to synch the computer clock to an accurate time source that does not depend on Internet connectivity.
