Reach:
Octal value. Indicates the status of the last 8 queries. The value "377" means that the last 8 queries were
successful.
Delay:
Value in ms. Displays the runtime of the NTP packet.
Offset:
The NTP software compares its own system time at regular intervals with its reference time sources. This
process is called "polling". After each polling operation, the packet trip time is determined, calculated, and the
current time difference ("offset") is calculated and displayed in milliseconds.
Jitter:
The packet trip time changes more or less depending on the characteristics of the network during the "polling"
of external NTP sources at each time comparison, and the calculated time offset also varies. For this reason,
the results of successive time comparisons are filtered by calculating weighted mean values for packet run time
and time offset. The deviations of the individual values from these mean values are referred to as "jitter", and the
higher the jitter value, the less accurate is the calculated time offset. On the other hand, a steadily increasing
mean time offset indicates that the system time drifts away from the reference time. The value is displayed in
milliseconds.
