Answer 1

Printing the current time from the internet time server

We make an example of NTPClient and afterward we call the demand() strategy on it by passing the NTP server address.

Writing an SNTP client

Give us a chance to make a plain SNTP customer without utilizing any outsider library.

Give us initial a chance to characterize two constants: NTP_SERVER and TIME1970. NTP_SERVER is the server address to which our customer will associate, and TIME1970 is the reference time on January 1, 1970 (likewise called Epoch). You may discover the estimation of the Epoch time or convert to the Epoch time at. The genuine customer makes a UDP attachment (SOCK_DGRAM) to associate with the server following the UDP convention. The customer then needs to send the SNTP convention information ('\x1b' + 47 * '\0') in a bundle. Our UDP customer sends and gets information utilizing the sendto() and recvfrom() techniques.

At the point when the server restores the time data in a pressed cluster, the customer needs a particular struct module to unload the information. The main intriguing information is situated in the eleventh component of the cluster. At long last, we have to subtract the reference esteem, TIME1970, from the unloaded an incentive to get the real current time.
