Questions tagged [time]

By Einstein's definition, time is what clocks measure – but how can we define “clock” without referring to time? This tag is for such philosophical questions about the many unresolved issues concerning time. Though this includes questions about the interpretation of physical theories and concepts, if your question is about what current physics can quantitatively predict or explain, it is probably not about philosophy and therefore off-topic.
