Time zone not working

It took a bit to realize that configTime() is an ESP8266-specific function:

esp8266/Arduino/blob/9913e5210779d2f3c4197760d6813270dbba6232/cores/esp8266/time.c#L58


      
          
          static void setServer(int id, const char* name_or_ip)
          {
              if (name_or_ip)
              {
                  //TODO: check whether server is given by name or IP
                  sntp_setservername(id, (char*) name_or_ip);
              }
          }
          
          void configTime(int timezone, int daylightOffset_sec, const char* server1, const char* server2, const char* server3)
          {
              sntp_stop();
          
              setServer(0, server1);
              setServer(1, server2);
              setServer(2, server3);
          
              sntp_set_timezone(timezone/3600);
              sntp_set_daylight(daylightOffset_sec);
              sntp_init();

Maybe look at Getting Time from NTP service using NODEMCU 1.0 (ESP- 12E) - #6 by bperrybap
