Connect to a NTP server, here is how:
#include <NTPClient.h>
#include <ESP8266WiFi.h>
const char *ssid = "<SSID>";
const char *password = "<PASSWORD>";
// By default 'time.nist.gov' is used.
NTPClient timeClient();
// You can specify the time server pool and the offset, (in seconds)
// additionaly you can specify the update interval (in milliseconds).
// NTPClient timeClient("europe.pool.ntp.org", 3600, 60000);
void setup(){
Serial.begin(11520);
WiFi.begin(ssid, password);
while ( WiFi.status() != WL_CONNECTED ) {
delay ( 500 );
Serial.print ( "." );
}
}
void loop() {
timeClient.update();
Serial.println(timeClient.getFormattedTime());
delay(1000);
}
