error: 'timezone' does not name a type

[tatuiot]

Hi , thanks for your library.
I managed to make it work commenting out the line
timezone timeZone; ///< @brief
But it happens that the time displayed is 6hrs ahead of the real time... It was working last week... but now... suddenly... it stopped working properly and I cannot make it work again.

I am using VSCode 1.62.1 / Platformio 5.2.3 / ESP32 Dev Kit1 / ESPNtpClient 0.2.5

uint8_t initNTP(void)
{
    NTP.setTimeZone(TZ_America_Argentina_Buenos_Aires);
    NTP.setInterval(600);
    NTP.setNTPTimeout(NTP_TIMEOUT);
    //NTP.setMinSyncAccuracy (5000);
    //NTP.settimeSyncThreshold (3000);
    NTP.begin(ntpServer);
    Serial.println(F("NTP CONFIGURED"));
    return 0;
}

I am lost... thanks in advance any tip please share...

here is the log output.

Hi, I managed to fix it using the following statement
NTP.setTimeZone(TZ_Etc_GMTm3);
there must be some kind of bug there because Buenos Aires time adds 3 hrs to GMT time and it should be -3.

[gmag11]

Encoding for Buenos Aires time is #define TZ_America_Argentina_Buenos_Aires PSTR("<-03>3"). I've found no reference for this format but https://developer.ibm.com/articles/au-aix-posix/ Notation using <> is not described there so maybe it is a mistake.

As Argentina does not have DST you can use GMT-3.

I've added an issue in ESP8266 Arduino core repository: esp8266/Arduino#8423
