This paper studies the effects of information technology on time and temporality in organizations. It starts with the proposition that time is not simply physical and natural, but social and socially constructed. When we understand time as a social phenomenon, another question comes up spontaneously: how information technology, the defining technology of the contemporary age, affects time. This paper explores the issue focusing on the effects of organizational information systems on temporality from the MIS perspective. It explains the social nature of time by examples in history, and reviews studies of time and information technology in organizations. Finally, it makes the following suggestions for further research on time and information technology: 1) more empirical research, 2) research based on social time, 3) study of time in the context of organizational culture, and 4) research integrating time and space.
