Lefebvre summarises this march of clock-time through society and nature (1991: 95–6). He argues that the lived time experienced in and through nature has gradually disappeared. Time is no longer something that is visible and inscribed within space. It has been replaced by measuring instruments, clocks, which are separate from natural and social space. Time becomes a resource, differentiated off from social space. It is consumed, deployed and exhausted. There is the expulsion of lived (and kairological) time as ‘clock-time’ dominates. Lefebvre describes this changing nature of time in terms of metaphor. In pre-modern societies lived time is encrypted into space as in a tree-trunk, and like a tree-trunk shows the mark of those years that it has taken to grow. While in modern societies time is absorbed into the city such that lived time is invisible or reduced to its methods of measurement. Lived time ‘has been murdered bysociety’ (Lefebvre 1991: 96).
