Over the past half century, time-use studies have become a leading method for researching unpaid care work, especially in the multidisciplinary field of gender divisions of household work and care and in feminist international studies on counting and accounting for women's unpaid work. Although attention to conceptual and methodological refinements in time-use methods is increasing, more focus on the challenges of conceptualizing and measuring care responsibilities, the limitations of measuring relational care practices with clock time, the existence of other kinds of time, and the epistemological and ontological moorings of time-use studies is needed. Two research programs inform this article: qualitative and longitudinal research with Canadian households in which parents were challenging norms, practices, and ideologies of male breadwinning and female caregiving; and the development of a feminist ecological ethico-onto-epistemological approach to knowledge making. A case study from the first program and several pivotal ideas drawn from the second-about relational ontologies, multiple ontologies, and the ethico-political dimensions of knowledge making-support three key arguments advanced in this article. First, I argue for a deeper interrogation of methodological and epistemological matters in coding, classifying, and categorizing care tasks in time-use studies. Second, I maintain that care responsibilities exist as "process time"; they can be narrated, but they cannot be measured in fixed units of clock time. Third, I maintain that it is not only possible, but politically and conceptually important for researchers to look beyond clock time, to recognize the ontological multiplicity of time, including relational and non-linear time and to embrace and use different kinds of time. This article is part of a growing call to reimagine how we think about, conceptualize, measure, and make knowledges about time, time use, and care-time intra-actions.
