When we uncomment the line local stratum 10 then makes our Linux Server as chrony NTP server and continue to work normally even if it is disconnected from network. Our email and other transactional searches were aided by log entries with timestamps thattodaycan resolve down to the nanosecond in even the slowest of modern Linux computers. To halt a system, issue the following command: Finally, to reboot a system, enter the following command: Similar to the emergency and rescue commands, these commands will issue a notice to all users that the system state is changing. Let's look at the current status of NTP on a virtual machine I use for testing. Eventually, it should stabilize with a tiny variation around a fairly small range of error.
