Time is one of the most important aspects of setting in Replay. Through his replays, Jeff explores the years of 1963 through 1988, experiencing how society and culture changes over time. He goes through the sexual and cultural revolutions of the 1960s, as well as the civil rights movement. Because Jeff goes to college in Atlanta, Georgia, he sees segregation and racial violence in the early 1960s when he returns to his college years. The death of John F. Kennedy marks an important turning point for Jeff in the late 1960s, and the Iran hostage crisis marks another important point as time moves forward.
