The command "chronyc tracking" is used to display various parameters related to the system's time synchronization with a reference time source.

When you run the command, it provides information such as:

1. Reference ID: This is the unique identifier of the time source your system is trying to synchronize with. It could be an IP address, hostname, or some other identifier.

2. Stratum: This indicates the stratum level of the time source. The lower the number, the more accurate and reliable the time source.

3. Ref time: It shows the time at which the reference time source was last updated.

4. System time: This displays the current system time on your computer.

5. Last offset: It indicates the time difference between your system clock and the reference time source. A positive value means your system's clock is running fast compared to the reference, while a negative value means it's running slow.

6. RMS offset: This is the root mean square (RMS) of the offset values measured over a certain period. It indicates the average difference between your system clock and the reference time source.

7. Frequency: This represents the frequency adjustment being applied to your system clock. A positive value indicates your clock is being slightly sped up, while a negative value means it's being slowed down.

8. Residual freq: It represents the average difference in system time frequency between your system clock and the reference time source.

By running the "chronyc tracking" command, you can get insight into your system's time synchronization status and assess how well it is keeping time with the reference source.
