I think a project manager must have time management and communication skills. The reason being is that for every project there are time limit. Project managements are responsible for meeting all report document deadline from their fellow departments, for example; regulatory, quality, marketing. Project manager must create schedules for meeting fellow departments and discussing, improving, and/or approving documents. This is where project managers communication takes place, they need to be clear and concise so other group members understand their task. Project managers are leaders and must guide the other group members in order to complete. If other members are stuck they must assist, because the project cannot move forward if one member is having problems in their task.
