Add and commit changes to a new branch and create a pull request ONLY TO YOUR OWN FORK to see the CI/CD build happening. If the build succeeds, merge the pull request with master and see the CI/CD `upload_zip` take place. 2. Add 2 more unit tests of your choice to `test_app.py` and make sure they are passing. 3. Add one more classifier to startup and use only the one with better accuracy. 4. Add the attribute `timestamp` to the response and return the current time with it.
