- Thu Jan 25, 2018 5:42 pm #73489 I'm testing code for simple local time retrieval found here: https://github.com/scanlime/esp8266-Arduino/blob/master/tests/Time/Time.ino

But it displays the date/time 21 hours into the future.
It has a Timezone value, set to 3 by default, but the result time is the same regardless of the Timezone value.
(I'm in the US, CST time zone (GMT-06:00))

Any code corrections appreciated.

Code: Select all#include <ESP8266WiFi.h>
#include <time.h>

const char* ssid = "..........";
const char* password = "..........";

int timezone = 3;
int dst = 0;

void setup() {
  Serial.begin(115200);
  Serial.setDebugOutput(true);

  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  Serial.println("\nConnecting to WiFi");
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(1000);
  }

  configTime(3 * 3600, 0, "pool.ntp.org", "time.nist.gov");
  Serial.println("\nWaiting for time");
  while (!time(nullptr)) {
    Serial.print(".");
    delay(1000);
  }
  Serial.println("");
}

void loop() {
  time_t now = time(nullptr);
  Serial.println(ctime(&now));
  delay(1000);
}

Thanks Martin.
I've been sitting here too long, without a break.

The original code had a '3' in the formula, not the 'timezone' variable.

Now I need to separate the time (hh:mm:ss) from Date (Jan 25, 2018)...

Good luck,
