Ntp library about esp8266-ntp-time-on-an-oled-with-wifi-manager HOT 4 CLOSED

Either would do, I just happened to pick on NtpClient, they look near identical, I'll check it out.

from esp8266-ntp-time-on-an-oled-with-wifi-manager.

OK, after further investigation I have determined there is little capability difference between the two libraries, although the NtpClient library you refer to needs an additional library of time.h so adding to the code overhead. There is no 'official' NtpClient' library as far as I know. Thanks for pointing out this other library.

Mmmm.

I am using the Arduino NtpClient Lib from here,

I am getting an error on this line.

NTPClient timeClient(time_udp,"time.nist.gov", TimeZone * 3600, 60000); // (logical name, address of server, time-zone offset in seconds, refresh-rate in mSec)

the error output is

ntp_test_3:33: error: no matching function for call to 'NTPClient::NTPClient(WiFiUDP&, const char [14], int, int)'

NTPClient timeClient(time_udp,"time.nist.gov", TimeZone * 3600, 60000); // (logical name, address of server, time-zone offset in seconds, refresh-rate in mSec)

Wrong library, this is the one I'm using: https://github.com/arduino-libraries/NTPClient

I've added the link to the readme too

Don't forget to remove the other library
