[SOLVED] Sending NTP time to KNX in OpenHAB2?

Hi,
I’m trying to replicate techniques presented here, but I’m missing something.
Here are my settings:

I defined virtual thing (I didn’t use datetime-control):

 Thing device Knx_virtual "KNX-virtual"  {
        Type datetime : date [ ga="11.001:2/1/2" ]
        Type datetime : time [ ga="2/1/1" ]
    }

item (time) definition:

DateTime Date  "Time [%1$tA, %1$td.%1$tm.%1$tY %1$tH:%1$tM]"  { channel="ntp:ntp:local:dateTime,knx:device:bridge:Knx_virtual:time" }

Thing is linked:

NTP service is running:

Time data is received and forwarded to Knx_virtual thing:

ETS device is linked:

I have restarted openhab in hope of that time is pushed to KNX bus when it is received first time- didn’t help.
How often is ntp time pulled from server?
I don’t understand why time is not pushed to KNX bus.
What am I missing?
