While I trying to compile the mentioned example code from the link, I'm getting this error message:
'gmtime' was not declared in this scope

https://randomnerdtutorials.com/esp8266-nodemcu-date-time-ntp-client-server-arduino/

I'm using Arduino IDE v1.8.2 with ESP8266 Core v2.3.0

Is there any workaround or maybe a standalone function for gmtime?

Thank you for your time and support,

Kind regards,
Viktor

Unfortunately, no, if you meant for this line/comment:
#include “time.h” at beginning of the code. Than compilation is OK.

It wont compile, but I used a fork of the NTPClient library and added some additional code to it.
From this page: https://randomnerdtutorials.com/esp32-ntp-client-date-time-arduino-ide/

So, combined two different source and extended the code, and it's solved my issue.

Thanks for the suggestions!
