This article makes two arguments. First, that advanced information and communication technologies (ICTs) have created multiple parallel flows of consumption that allow us to be productive continuously, in the sense of generating value for the economy. Second, the struggle over social time poses emergent challenges for planning and urban design. After introducing the relevant themes, this article explains how value is derived from labour and the process through which time is made economically productive. Next, it is posited that advanced ICTs, (...) especially mobile devices and associated services, create possibilities for multiple flows of time, freeing consumption from territorial and temporal restrictions, and opening up new forms of labour. This discussion elicits some concerns for those interested in communities and urban space. The article concludes with suggestions for adopting a socio-spatial-temporal outlook to urban planning and design, including designing ‘polyrhythmic’ places and planning for public time. (shrink)
