Hi, the correct way to *change* to a namespace is in-ns. Calling ns will also refer to clojure.core. The first scenario happens because the namespace already exists and the ns tries to refer extend to #'clojure.core/extend which fails because #'clj-time.core/extend is already there. The second scenario happens because the namespace did not exist before. So the ns form sets up everything as normal. Now loading the file will refer extend to clj-time.core/extend. This will only give a warning because now clojure.core/extend is replaced and clojure.core gets special treatment here by giving only a warning instead of an exception.
tl;dr: Use ns to setup a namespace. Use in-ns to switch namespaces. In your case: (in-ns 'test.core).
