This repository is an implementation of a (really) trivial NTP client in Go. It uses the encoding/binary package to encode and decode NTP packets sent to and received from a remote NTP server over UDP. You can learn more about NTP here, read the specs RFC5905, and find a (seemingly) way better Go NTP client, with many features implemented, here.
The code is explained in this writeup titled Let's make an NTP client in Go.
