Is Time::SetTime a static member function? You didn't give the
definition in your E-Mail so I can't tell..

If it isn't, then it is a class method, and requires a hidden *this
parameter.

Furthermore, if it is a virtual function, then a static binding may
not be appropriate.

Check the GNAT reference manual for details on the following pragmas
(section 10.2 Interfacing to C++):

pragma CPP_Class
pragma CPP_Constructor
pragma CPP_Vtable

Note I haven't used any of these, don't understand (yet) how to use
them, and I don't know of any examples (do a web search).
