3 years ago First of all, I hope you realize that solar calculations require the time reference to remain in UTC time (in this case your RTC). If you want to display local times for solar positions with boards that use the AVR processor (including the UNO), the easiest way to get local time is to use a time zone library, such as Jack Christensen's:
https://github.com/JChristensen/Timezone
Again, the RTC must remain set to UTC.
Thanks, Ken

I'm working on simple heliostat project, and I've found this library very useful. but very difficult to understand for me. I'm using RTC (DS3231) and Arduino Uno. with the example sketch "solarTmeRTC" which is working perfectly with my lat and long. the only issue is "I can't convert UTC to local time (+5.5)" could you please help me to get the local time
thank you...
