To install NTP on Linux and update the system time automatically from the Internet, firstly install the NTP client.
[email protected]:~$ sudo apt-get install ntp
Then install the ntpdate utility.
sudo apt-get install ntpdate
Then you may synchronize the time on your machine with the Internet time server.
[email protected]:~$ sudo ntpdate -s time.nist.gov
[email protected]:~$ ntpstat synchronised to NTP server (18.104.22.168) at stratum 3 time correct to within 191 ms polling server every 256 s
This is how easy it is to synchronize the time on your Linux machine with an Internet time server. This is very important when the machine is a server and connected to the Internet.
