NTP client in C++ (compatible with chrony)

NTP client

This is a C++ class that implements a NTP client. It has been tested with a chrony server. I have also included a sample of my chrony.conf file where I have setup a local server and client for my experiments.

build

First create an empty directory inside your working folder:

mkdir build && cd build

and then

cmake ..

and

cmake --build .

Optional, if you want to install:

make install DESTDIR={YOUR_INSTALLATION_PATH}

By default, the installation path is /usr/local/
