16.10 NTP
To activate the NTP auto synchronization set a not zero value in AutoRequest Time.
After a modification of this parameter or a modification of the NTP IP address, the Wolf2MS will try to synchronize the
system clock. After the first synchronization, the server will be contacted automatically with the selected period in
minutes.
After a system reboot or restart, if AutoRequestTime is activated, in the first operative minute the NTP-V3 server will be
contacted, as well as after the selected period.
The NtpSynch status starts as OK(synchronized) at the system startup, but after the first synchronization attempt it will
show the real status. Every NtpSync status variation is signaled (if enabled) with the NtpFailureNotificationTrap.
An NTP synchronization failure will be indicated with a red alarm line under the Date/Time field.
Modified the behavior of the NTP client in the release 0.6.5. Peer Polling interval is set now as 4 (16 sec) in place of 3 (8
sec). If the timing adjustment is less than 5 seconds the sysclock will be adjusted in a slow continuous way (about 2
sec/hour) avoiding sysclocks jumps (very important for the streaming, will be documented in the manual) and the
recommended synch period should be at least one per day
