This article investigates teachers' lived experiences of an online professional development (OPD) course in Denmark – that is, Teknosofikum – through a hermeneutic phenomenological perspective, and it relies on the interpretive analysis of 15 semi‐structured interviews. The article's contribution focuses on the theme of ‘time’ and highlights it as a multifaceted construct that plays a relevant role in learning. By relying on the ideas of temporal structuring and multiple temporalities, the article shows that OPD courses and HE teachers' engagement nest themselves into pre‐existing and complex nexus of commitments and duties, each of which has its own temporality and rhythm, along with longer‐term aspirations for pedagogical development. As time emerged as a relevant aspect characterizing OPD course design and HE teachers' experiences, the article provides simple recommendations for ‘time‐aware’ OPD courses.
