[KNX] Send DateTime DPT19.001 error

Hello all,
I am trying to send DateTime to my KNX installation. I have followed some issue github to try to write things/items as it should. However I still see an error in the openhab log.
Can you help me?

knx.things

Bridge knx:ip:EIBMarket001 "EIBM KNX/IP Tunnel" @ "KNX" [
    ipAddress="192.168.1.35",
    portNumber=3671,
    localIp="192.168.1.2",
    type="TUNNEL",
    readingPause=50,
    responseTimeout=10,
    readRetriesLimit=3,
    autoReconnectPeriod=30,
    localSourceAddr="0.0.0"
] {

    Thing device knx_virtual "KNX-virtual" @ "KNX"{
        Type datetime-control : DateTimeKNX [ ga="19.001:7/4/0" ]
    }

default.items

DateTime DateItem "Date [%1$tA, %1$td.%1$tm.%1$tY %1$tH:%1$tM]"  {channel="knx:device:EIBMarket001:knx_virtual:DateTimeKNX", 
channel="ntp:ntp:local:dateTime"}

Thank you in advance for your help.

I have solved a bit my issue.
I have two openhab servers on the network (I am trying to make sure I can backup on to the other).
Thus it created this issue. When one server send the DateTime, the other one found a problem to decode it. That is why half of the messages are sent, and the other half is with issue.
I don’t know if it is a bug or only my non typical installation.
