Just as liquids conform to the vessel that contains them, time is shaped by the social, technological, and political forces of its era. The modified printers in this work continuously print five definitions of time units: from the contemporary definition of a second to the rhythm described in a Sanskrit treatise on astronomy, the medieval monastic moment or the nanocentury a measure created by IBM at the beginning of the computer age. The redefinition of the second in the coming years invites us to consider how we might define future units of time and what rhythms of life have imposed these different measures.
