In this video, we will talk about the built-in RTC chip that is included in every ESP32 microcontroller.
This RTC is easy to use but it's not the most accurate clock in the world. After a few days,
the time on this built-in RTC noticeably lags behind.
I have used this method many times, but I have never explained it properly. So, the method we use is to
connect our ESP32 to the internet every few hours, fetch the exact time, and set the built-in clock.
