There seems to be a typo in _hla/_rti/rtiambassador.cpp:

at line 705:

if(!PyArg_ParseTuple(args, "O&O&s|d",
        RtiInteractionClassHandle_FromPython, &theInteraction,
        ParameterHandleValuePairSet_FromPython, &theParameters,
        &theTag,
        RTIfedTime_FromPython, &theTime))
        return NULL;

I think the format string argument should be "O&O&s|O&"
RTIfedTime_FromPython is a python object not a mere double value.

at least UAV does it this way.
Are timestamped UAV ok?
