The purpose of the setup () function in this code is to establish a connection to the local Wi-Fi network and then to establish a connection to the pool.ntp.server (Figure 3). Learn how to display time on OLED using Arduino, DS3231 or DS1307 RTC module. This protocol synchronizes all networked devices to Coordinated Universal Time (UTC) within a few milliseconds ( 50 milliseconds over the public Internet and under 5 milliseconds in a LAN environment). After the connection is established, the ESP32 will submit a request to the server. UPDATE! NTP is an abbreviation for Network Time Protocol. The NTP Stratum Model starts with Stratum 0 until Stratum 15. Then, using the strftime() method, copy the information about the hour from the timeinfo structure into the timeHour variable. The function setSyncProvider(getTimeFunction) is used by the Time Library to call the getTimeFunction at fixed intervals. The second way is to use jumpers and connect the ICSP headers between the boards. Time format for HTTP header is always in GMT (UTC). Most Arduinos don't have any concept of the current time, only the time since the program started running.
