Hello everyone.
Then I used IPC-HDB4300C with Software Version 2.420.0006.0.R, build : 2015-03-11 I have had the problem with synchronization via NTP (time) servers.
The problem was solved then I upgraded to software Version 2.420.0008.0.R, build : 2015-07-10.
Somebody knows where I can find changes in different versions of firmware
Thanks in advance
