A typical time control is "60 minutes + 30 seconds byo-yomi", which means that each player may make as many or as few moves as they choose during their first 60 minutes of thinking time, but after the hour is exhausted, they must make each move in thirty seconds or less. To enforce byo-yomi, a third person or a game clock with a byo-yomi option is necessary.
