In many projects (Arduino IDE), we need accurate local time. With our ESP chips, we have some libraries to get NTP time, as I showed in video #67. Most of these libraries do not adjust for daylight-saving or summertime. Today we will change that by using standard ESP functionality. And we will see if Hippies were involved in this matter.
