Ancient Sibyls, such as the famous Pythia, frequently responded to supplicants' questions in a dark and mysterious way. (Croesus, for instance, was told that attacking the Persians would "destroy a great empire"; that this could also mean his own did not occur to him.) I was reminded of this by looking at the Javadoc for the org.drools.time.SessionClock method getCurrentTime, which is documented to return a long value, albeit explicitly stating that the semantics of this value is not defined and that an implementation of this interface may do as it pleases. All that's needed to clear this oracular obfuscation is another method, giving the number of nanoseconds per unit of the getCurrentTime return value. Why ever has this not been added? -W
