It is as many, or as few, hours as they want it to be, it is an elected position. They all have a full-time aide (or more) to do the office work. Many blow off committee meetings that occur during the day, too. Most of them have other full-time jobs, or even jobs (like King's and Downard's) that are likely more than what we consider full-time. But those two, specifically, like Tandy, can probably control their schedule more than someone like DJ and Kramer, who work jobs with set hours.
