  1. Install ntp package 
    apt install -y ntp ntpdate
  2. Edit '/etc/ntp.conf' file and append time.google.com server as follows: 
    server time.google.com
  3. Set correct time on current system using: 
    ntpdate -b time.google.com
  4. Start and enable ntp service 
    systemctl start ntp
    

    systemctl enable ntp
  5. Check status of ntp service 
    systemctl status ntp
    

    ntpq -p
    We should see at least one server with st value less than 16 (Preferably less than 6).
    In the ntpq -p output first we may see list of pools. The servers from the pool get listed later. It takes a while for pool list to populate.
