During the majority of this season, the 24 on-screen ticking clock appeared during various commercial breaks with an announcer voice saying, "It's a whole new day. Jack will be right back." The clock served to remind viewers that, even though they were watching commercials, time in the 24 universe still continued to tick. The clock was dropped near the end of Season 2 and was not used again.
