 After installing the NTP protocol, we have to configure the daemon in order to broadcast the correct time to the network. The configuration file for NTP is located at `/etc/ntp.conf`. In servers block, you should add a few extra lines to the bottom of your servers list to provide your current local time as a default should you temporarily lose Internet connectivity:
