Hi,
you are trying to derive from a functor.
Try this instead:
functor
import Time at 'Time.ozf'
export AgentTime
define
class AgentTime from Time.time
The class "Time" is exported at the feature "time" of the functor at "Time.ozf".
If you import the functor at "Time.ozf" as "Time", you need to access
"Time.time" to get access to the class.
I think your confusion might be related to the Java convention where file name
equals class name. In Oz, there is no such convention.
Cheers,
Wolfgang
