Getting Time From Internet Using ESP8266 | NTP Clock Project With ESP8266 Nodemcu: In this tutorial we’ll see how to get time using the ESP8266/nodemcu with Arduino IDE. Getting time is especially useful in data logging to timestamp your readings. If yo
NTP获得UTC的时间来源可以是原子钟、天文台、卫星,也可以从Internet上获取。这样就有了准确而可靠的时间源。时间按NTP服务器的等级传播。按照离外部UTC 源的远近将所有服务器归入不同的Stratum(层)中。Stratum-1在顶层,有外部UTC接入,而Stratum-2则从Stratum-1获取时间,Stratum-3从Stratum-2获取时间,以此类推,但St...
