This essay discusses the meanings of time at contemporary society. For doing so, first introduces a brief History of the social construction of the linear time as well the dissemination of the clock on Western society. The absorption of the clock time had a long span of approximately three centuries but this time is perceived nowadays as absolutely natural. The clock time organized institutions and social live, specially the industrialized societies. At the second part, we argue that as clock time organized industrialized societies the computer is the symbol of time at contemporary societies. The time of computer is not linear but simultaneous and instantaneous. Differently from linear time of the clock, the time of the computer is multiple, flexible but also an agency of oppression and anxiety. Finally we argue what could happens to people, to institutions and to social live, when people finally incorporate this multiple time of computer.
