What is NTP in Timedatectl?

NTP is a TCP/IP protocol for synchronizing time over a network. Basically a client requests the current time from a server, and uses it to set its own clock. Ubuntu by default uses timedatectl / timesyncd to synchronize time and users can optionally use chrony to serve the Network Time Protocol.

4. Execute ntpstat to determine the ntp time synchronization status.

What clocks does the Timedatectl command expose?

On Oracle Linux systems, use the timedatectl command to set the system date and time. The command updates the real time clock (RTC), also known as the hardware clock, as well as the system clock that is maintained by the system kernel.

2. In the Configure NTP servers window, select New.
3. In the NTP server field, enter the IP address or URL of the NTP, which you want to set the time synchronization with.
4. Click Ok.
5. Select Continue.

How do I know if chrony is running?

To check if chrony is synchronized, use the tracking, sources, and sourcestats commands. Run the chronyc tracking command to check chrony tracking. Alternatively you could run chronyc to display a chronyc> prompt, and then run the tracking command from the chronyc> prompt.
