Introduction.
Today, so many things depend on accurate time-keeping. Thus we don't need to disable time sync usually, but sometimes -- workaround to annoying GPSD bugs and so on -- we need to disable it.
In the past, it was common to use ntpd for time sync. Since systemd-216, the systemd-timesyncd is often used.
