Almost all theatrical productions rely on a certain amount of suspension of disbelief; one of the dramatic factors which require that suspension is the timeline over which a show takes place. Most plays and musicals are divided into acts and scenes, with the potential for significant jumps in time between them.
However, there are also shows that feature no time jumps at all and instead take place within the specific window of time necessary to perform them, or "real-time." Some are plays set in offices, living rooms, dining rooms, or bedrooms, such as Who's Afraid of Virginia Woolf or God of Carnage; others are musicals set up as a concert, such as Hedwig and the Angry Inch. Even Andrew Lloyd Webber's Cats, which features the unbroken action of a single night in a junk yard, falls within this category.
