We learnt how to receive date and time from an NTP server using an ESP32 programmed with the Arduino IDE in this lesson. Epoch time, or Unix time, is a time reference commonly used in computer systems. I saw documentation and examples about clock but I don't find anything that can . To know what the time "now" is you have to have some mechanism to tell the Arduino what the time is, along with a method of keeping track of that time. You don't need a pullup resistor, as we will use the one built into the arduino using the INPUT_PULLUP command. NTP (Network Time Protocol) The Ethernet shield will give the Arduino board network connectivity. If you are willing to get current Time and Date on the Arduino Serial monitor you can start working with RTC (Real Time Clock) module, which are available easily in the local as well as online stores. These two wires are used to set the time and retrieve it. function () if year~=0 then print (string.format ("%02d:%02d:%02d %02d/%02d/%04d",hour,minute,second,month,day,year)) else print ("Unable to get time and date from the NIST server.") end end ) Enough to use the SD card? Then, using the strftime() method, copy the information about the hour from the timeinfo structure into the timeHour variable. The NTP server then adds its own timestamp to the request packet and sends it back to the client. They are cheap and easy to use modules. Arduino Stack Exchange is a question and answer site for developers of open-source hardware and software that is compatible with Arduino.
