The clock synchronization on Ubuntu

sudo apt install -y ntp ntpdate ntpstat
sudo ntpdate -s time.nist.gov
sudo service ntp restart
ntpstat

maint.clock.time: clock base time (unix time)

Output

{
  "clock": {
    "sync": {
      "status": "synchronized"
    },
    "diff": {
      "time": 100,
      "dangerous": true
    }
  }
}

clock.sync: clock synchronization

clock.sync.status: clock synchronization status

synchronized: clock is synchronized

unsynchronized: clock is not synchronized

indeterminant: clock state is indeterminant

clock.diff: clock difference

clock.diff.time: clock difference in milliseconds

positive value: behind of time

negative value: ahead of time

clock.diff.dangerous: if the difference is big enough to be considered dangerous
