With DevTest 10.1, the meta-data property lisa.ibmmq.Recv.MQMD.PutDateTime is no longer available. It was split into two meta-data properties:
lisa.ibmmq.Recv.MQMD.PutDate
lisa.ibmmq.Recv.MQMD.PutTime
However, the lisa.ibmmq.Recv.MQMD.PutDate property is giving the wrong date. It is one month off.
We may have a patch to address your issue. Please open a support ticket and reference DE307219.
We will be happy to provide you the fix if it matches your issue.
