Obviously, this error has been more than 1000 seconds, and when the operating system and superior NTP can sync with the prerequisite requirements-the difference between the two is less than 1000 seconds, when the time lag is greater than 1000 seconds, the Linux operating system will "suspect" superior NTP, so automatic synchronization aborted, Avoid the exception of the superior NTP server that affects your system.
