Abstract: Precision digital chronography based on detected changes in state of a processor is described. The changes in state may be detected by another processor and an averaged time interval generated. A signal corresponding to the averaged time interval may be communicated to a distributed database and propagated to remote systems. Devices associated with the remote systems may adjust or set a device clock in accordance with the averaged time interval.
