8.3.3.1 System Info
In the window "System Info" the current NTP values of the NTP service running on the em-
bedded Linux of the Time Server 8030HEPTA/GPS are indicated. In addition to the NTP cal-
culated values for root delay, root dispersion, jitter, and stability the stratum value of the Time
Server 8030HEPTA/GPS, the status to the leap second, and the current system peer are also
found here.
The NTP version used adjusts the leap second correctly.
The Time Server 8030HEPTA/GPS works as NTP Server with stratum 1 and belongs to the
best available class of NTP server, as it has a reference clock with direct access.
8.3.3.2 Kernel Info
The “Kernel Info” overview shows the current error values of the internal embedded Linux
clock. Both values are internally updated every second.
This screenshot shows a maximum kernel clock error of 1.500 msec (milliseconds). The esti-
mated error value is 1
μs (microseconds).
The values indicated here are based on the calculation of the NTP service and have no sig-
nificance for the accuracy of the Sync Source (here Module 8024GPS).
