Thank you for your reply. There is another question. What is the difference between two clock sources to make them trust each other? After all, the difference of 65 ms can be ignored in some scenarios.

These two sources don't agree with each other. They are about 65 milliseconds apart. chronyd doesn't know which one (if any) is correct. That's why normally is recommended to have at least three sources. You can mark one with the "trust" option to force chronyd to select it.
