Re: Ntp Sumertime changes at the Amerikan Date
No such thing, you're probably using a 3rd party lib, one from a different SDK, or the ESP-IDF POSIX built-in functions. In case of the last, refer to the manual. In case you don't use that, please specify what you do use.Esp32's time Lib

Honestly I am a bit confused, what im using, because i use the one which comes with the esp32 i just include time.h and the functions are the same like in ESP-IDF POSIX but the ntp syncronization is done differently. I folowed the guide on https://randomnerdtutorials.com/esp32-d ... r-arduino/

The arduino function configTime does not let you set the dst rule and so defaults to US rule

However, I think you should still be able to set the timezone using the TZ variable; refer to the manual page I linked earlier. Specifically, something like
and then using 'localtime' to get the time should work.
Code: Select all
// Set timezone to China Standard Time
setenv("TZ", "CST-8", 1);
tzset()
