Hourglass

We are in the process of evaluation of IBM HourGlass V7 undr zOS.
In batch it is working fine : Natural programs are getting the altered date/time.
Under CICS this is not the case. Verification tests provided in IBM doc are ok but Natural programs do not get altered date/time.
Interface with NAtural language is not documented any more by IBM amd I could not find any related topic in Empower.

Any help will be much appreciated,
