Make time values understandable before relying on their order. These articles explore event time, observed or collected time, source clocks, sequence numbers, and file behavior. They are relevant whenever delayed delivery, clock differences, or a restart can make an apparently simple timeline difficult to interpret.
Begin with the data logger guide for representation and units, then connect those decisions to an event schema and collection workflow. An unambiguous timestamp format helps a reader interpret the value; clock accuracy and causal ordering still require their own evidence and operating assumptions.
