Teresa Brennan separates the social time of labour and production, from a natural reproductive time. Social time is furthermore characterised as artificial time, which via the speed of the acquisition of money (capital) diminishes or degrades natural reproductive cycles.

Money…is essentially time. Marx measured money in terms of labour-time, but by this argument it should be measured in terms of the speed of acquisition. Thus inflation and interest would be the measures of distance between sources of energy and the speed with which they are consumed, a measure which intersects with reproduction, especially but not only that of labour-power. We will regard money, then, as the phenomenal form of the socially produced time of speed, rather than of labour-time as such. This retains some of the reasoning behind Marx’s definition of money, although that definition conflated the social time of production with natural reproductive time, and it is these we are separating in this redefinition of the relation between value and price. The price of a commodity becomes inflated the further removed it is from its value, and especially inflated if its production has removed the source of value altogether. The price of money, measured in interest, would be affected by the same variable. Once more, time, as money and speed, literally encapsulates the natural energy whose flourishing it must diminish. For if the quantity of use-value overall as the basis of surplus-value is diminished, as I have argued it must be, something has to take its place. This something is the creation of an artificial space-time. This creation is the means whereby money rivals natural time in its imitation of reproduction.

Short-term profitability, with its inflated price, must lead to a diminution in long-term profit and productivity. In that the substantial material embodiment in productivity and profit has to be reduced or rendered unreproducible by the logic of production geared to speed, capital is its own worst enemy. How this is played out in total terms should be reflected in the crisis of capital, in its ‘long waves’ and ‘laws of motion’. In sum, what Marx saw clearly and before all was the inherent contradiction in capital as a mode of production. He saw it in terms of labour and technology, or constant and variable capital, as he defined it, where the former, to keep pace, had to expand at the expense of the energy input of labour. The contradiction is recapitulated in this account, although its terms of reference have changed. Or rather, its terms of reference have been stripped of their phenomenal forms, so that the contradiction emerges as what it is essentially: one between substantial energy and artificial speed. Yet we have established that the contradiction between energy and speed is not simple. Two forms of time are at issue: the generational time of natural reproduction, and speed, the artificial time of short-term profit. Speed, as I have already indicated, is about space as much as time as such. It is about space because it is about centralization and distance. Speed, measured by distance as well as time, involves a linear axis, time, and the lateral axis of space. In what follows, I will begin by emphasizing how, in the consumptive mode of production, the artificial space-time of speed (space for short) takes the place of generational time. For to the extent that capital’s continued profit must be based more and more on the speed of acquisition, it must centralize more, command more distance, and in this respect the artificial space-time of speed must take the place of generational time.

It is clear that generational time suffers because capital tends inevitably to speed up the production of all commodities, including naturally formed or agricultural ones. While there are countervailing tendencies in agriculture and labour-power, in terms of scarce or apparently irreplaceable sources, the speed imperative will override them wherever possible. As production speeds up, it is also clear, capital will diminish or degrade the conditions of the specific or overall natural reproduction of natural and agricultural products. But this is not the only way that generational time is short-circuited by short-term profit.

Jonathan Martineau describes capitalism’s commodification of time according to measures of commercial value as having alienated humans from the concrete time  that is associated with bodies, emotions, and the ecosystem. In reducing time to calculations of market based exchange value, capitalist, abstract, clock-time, is said to be separate from what is naturally individual about time.

Although I have focused on capitalist abstract clock-time, throughout this study I have kept alive notions of concrete times. I have highlighted the temporal aspect of dynamics of domination and resistance between capitalism’s tendency to commodify – and therefore alienate – time, and the concrete times of human lives and socio-natural processes that resist it. Capitalism’s drive to commodify and alienate time is relentless, and it is expressed in processes occurring all across the social field. Indeed, the drive toward the privatisation of natural resources can be read as an attempt by capital to abstract the concrete times of socio-natural cycles in order to ‘valorise’ them, i.e. to integrate these times in the logic of capital accumulation. In such processes of commodification, the complex cluster of useful labour, socio-natural cycles, human bodies and concrete temporal relationships become means to an end: capital accumulation…Examples such as these with regards to the relationship between humans and a socially mediated nature, between humans and humans, and between humans and their own bodies, illustrate a struggle between capitalism and human lives, of which the temporal dimension deserves more attention from critical scholarship.

Perhaps we can now propose a solution to the modern paradox of time with which we started this enquiry. Why, in a context where time is measured and organised to such an unprecedented degree, is it experienced by us as the most uncontrollable and alien force? The measuring and organising of time is a social need; it is a fundamental component of the organisation of society and also of the reproduction of the human species. However, under the compulsion of class relations, and today of capitalism, social time relations have been serving the interests of dominant powers, often at the expense of the concrete times of exploited or oppressed groups. The power of capital in modern societies has relied heavily on the development and refinement of the measurement and organisation of time to an unprecedented degree. The first purpose of this measurement and organisation, however, is to reproduce the power of capital and to increase the power held by the law of value over social relations, not to enhance the potential of humans as world-making and time-making beings. As such, measured and organised time faces us as an alien structure, coordinating value relations instead of facilitating human relations and contributing to human development.

Measured and organised time therefore goes hand in hand with its alienation in our modern temporal order for the simple reason that time is measured and organised not by us, but by capital, not for us, but for capital. Our times are therefore subject to the imperatives of the law of value. Reclaiming human concrete times of emotions, work, social relationships, human bodies, friendships, love, parenting, childhood, laughter, sleep, childbirth, childrearing, food production, art, the concrete time of our ecosystems, and so on, thus forms an integral part of the reclaiming of our lives and our world. The struggle for ‘decommodification’, to employ a somewhat rebarbative term, also entails a struggle for the decommodification of human and socio-natural concrete times, the end of temporal alienation and of the subjection of human and social lives to the dictates of the capitalist market, capitalist abstract clocktime compulsions and capital accumulation (Martineau 2015, 167-68).
