Adjust the time by manipulating the clock-like interface. 2. Choose the places that are available for Bob by clicking on the map. (a) Click on a new place to create a new one. At the same time, you can edit the place's radius and name, such as STATA or Boston. (b) Clicking on an existing place can either delete it or edit it. 3.
