The relationship between time and international law is intricate and multifaceted, long evading methodical analysis. However, recent years have seen a surge in scholarly efforts to address this relationship. Taking a broad view of this burgeoning literature, this article recounts the temporal assumptions, narratives, and dynamics at play in the international legal sphere, while highlighting their logics and limitations. In doing so, it develops a critical typology of international law’s temporalities, distinguishing between three overarching paradigms: modern, postmodern, and hypermodern. The modern temporal paradigm, commonly seen as dominating the discipline, views international law as progressing uniformly and linearly from a dark past toward a brighter present and future. In contrast, the postmodern paradigm challenges the modern narrative of universal progress over time, shifting the focus to the past and the ways in which international law allows past wrongs to reverberate into the present. While each of these paradigms serves important functions, the article argues that neither provides a sufficient framework for navigating international law in the current era of accelerated technological, social, and environmental change, where the future increasingly diverges from the known past and present. The article thus calls for greater incorporation into the discipline of a third, hypermodern temporal paradigm, which takes a sober look at the future and recalibrates international law’s temporal modalities in response to rapidly evolving and increasingly complex global challenges.
