ESP8266 NTP CLOCK

摘要

To overcome the problems with manual time, date setting, and time drift, many so called "atomic clocks" or "radio controlled clocks" have appeared on the market. They come in just about every conceivable shape and size. These clocks listen for WWV radio transmissions from Fort Collins, CO, and synchronize their time keeping mechanisms to the atomic clock reference used for these transmissions. This helps guarantee their time keeping accuracy. Clocks like these typically require the user to select their time zone, but other than that do not offer any controls for manually setting the time.
