The NTP Stratum Model starts with Stratum 0 until Stratum 15. UPDATE! The time.h header file provides current updated date and time. On the other hand, Stratum 2 NTP servers connect to one or more Stratum 1 servers or to other servers in the same stratum to get the current time. I'm sure it can be done. The NTP server then adds its own timestamp to the request packet and sends it back to the client. This reference date is often used as a starting point to calculate the date and time of an event using a timestamp. Restart Arduino IDE for the next step. Great job, it worked great for me. Thanks for contributing an answer to Arduino Stack Exchange! Assign a MAC address to the ethernet shield.
