The ESP32 is an NTP Client in this example, requesting time from an NTP Server (pool.ntp.org). The NTP Stratum Model starts with Stratum 0 until Stratum 15. Connect it to your internet router with a Ethernet cable. Most people have their computers set up to do this, now the Arduino can as well. Configure the time with the settings youve defined earlier: configTime(gmtOffset_sec, daylightOffset_sec, ntpServer); After configuring the time, call the printLocalTime() function to print the time in the Serial Monitor. Drag the TCP Client from right to the left side and Under Properties window set. The NTP server then adds its own timestamp to the request packet and sends it back to the client. When pressing the button, the system connects to the local wifi and retrieves the current date and time from a remote network time server via NTP. Our project will request the IP from the DHCP, request the current time from the NTP server and display it on the serial monitor. You can also visit the WiFiNINA GitHub repository to learn more about this library. I found 5 x boards pre-assembled with the clock chip, including battery holder, crystal, chip, and circuit board for $US 4.20 on eBay. Some NTP servers are connected to other NTP servers that are directly connected to a reference clock or to another NTP server. The answer from the NTP server is the number of seconds since the life of Unix began which is pegged as midnight, 1 January 1970. You can't. For our project, we will use three libraries the SPI library, the Time library, and the Ethernet library. strftime(timeWeekDay,10, %A, &timeinfo); You can test the example after inputting your network credentials and changing the variables to alter your timezone and daylight saving time. See Figure 2 below as a guide. const char* ssid = REPLACE_WITH_YOUR_SSID; const char* password = REPLACE_WITH_YOUR_PASSWORD; Then, you need to define the following variables to configure and get time from an NTP server: ntpServer, gmtOffset_sec and daylightOffset_sec. First, we need to read a switch to determine the format, then we need to switch some code based on the results of that read. A basic NTP request packet is 48 bytes long. Filename Release Date File Size; Time-1.6.1.zip: 2021-06-21: 32.31 . Are you getting a time close to midnight, 1 January 1970?
