Time and media inherently possess a unified dual relation,mutually defining each other:without the visibility of media,time remains an inaccessible abstract concept;without the temporality of time,media ceases to be media."Mediating time"and"temporalizing media"are two fundamental threads for understanding the relation between time and media.The former refers to the various forms of time generated through the mediation of media technologies,while the latter analyzes the mechanisms through which media regulate and create the human perception of time,and this involves both the operation process of media based on time and the technical mechanism by which media construct"temporal forms".In today's world,these two threads converge,and the existing temporal frameworks are all imprinted with"machines'trace".The scale of time no longer accommodates human existence,and"timelessness"emerges as a defining human condition.
