This paper enquires into the history of clock-time through a critical engagement with Paul Glennie and Nigel Thrift’s Shaping the Day. The paper delineates the contours of an approach to the history of clock-time based on an analysis of the parallelism between the historical trajectories of clock-time and market relations. This approach is presented through a four-fold critical engagement with Glennie and Thrift's book assessing theoretical shortcomings, definitional problems, normative commitments and historical method.
