To get time from an NTP Server, the ESP32 needs to have an Internet connection and you don't need additional hardware (like an RTC clock). Before proceeding with this tutorial you need to have the ESP32 add-on installed in your Arduino IDE: Installing the ESP32 Board in Arduino IDE (Windows, Mac OS X, Linux Then get the time from startup with millis(), and add one to the other. So for example, if you started up at 9 am on 4th June, and 4 hours have elapsed, clearly it is 1 pm. You might reset the time (get it again from the NTP server) every 24 hours or so to allow for timer drift Obviously, from Arduino UNO to ESP32 has internal clock which are actually usable for ordinary works. But when we are already connected to the internet (we means ESP32), then fetching the time will give approximate closer value of event, such as button press. In real life, button press and fetching the time will have few seconds to few minutes time difference Now restart the modem using Software Restart command AT+CFUN=1,1 or you can hardware restart it. AT+CFUN=1,1 Now you can see after Call Ready there is a new line *PSUTTZ: which won't be there during normal startup. It shows the date and UTC time Arduino under the hood is just GRUN: I just get the internet time from any popular website (say google) by checking the http response header Date parameter. From a quick Google there is an example of using this approach of getting the time from the HTTP Date header using ESP AT commands here. Learn how to request date and time from an NTP Server using the ESP32 with Arduino IDE. I am.
So to get the time from Internet, we have to define three variables in our program for NTP. NTP_OFFSET which is the time zone of your country i.e. for India it is +5:30 hour. So it is 19800 in seconds. NTP_INTERVAL which is time interval taken by NTP to update time . When pressing the button, the system retrieves the current date and time from a network time server.

I discussed the advantages of using a real-time controller in your Arduino project in a previous post. In this post, I'll walk you through the basics of how to connect the DS3231 and establish communications with it. If you want to go further, there is another post showing how to build an Arduino alarm clock using the DS3231.. The DS3231 IC has only 8 functional pins The micros function, like the millis function, except it measures the time the Arduino has been running in microseconds. You can use the above functions to insert time delays or measure elapsed time. But you can't get the time of day or date from them. To do that you'll need to add an external component - a real time clock. Real. The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks.In operation since before 1985, NTP is one of the oldest Internet protocols in current use.NTP was designed by David L. Mills of the University of Delaware.(cit. wiki) NTPClient Librar Permanent Redirect.
Some Arduino projects may improve its functionality by calculating sunrise and sunsets times or current moon age.
