2. Trusted timestamping - Wikipedia

   en.wikipedia.org/wiki/Trusted_timestamping

   Trusted timestamping is the process of securely keeping track of the creation and modification time of a document. Security here means that no one—not even the owner of the document—should be able to change it once it has been recorded provided that the timestamper's integrity is never compromised. The administrative aspect involves setting ...

   In video production and filmmaking, SMPTE timecode is used extensively for synchronization, and for logging and identifying material in recorded media.During filmmaking or video production shoot, the camera assistant will typically log the start and end timecodes of shots, and the data generated will be sent on to the editorial department for use in referencing those shots.

7. Timestamping (computing) - Wikipedia

   en.wikipedia.org/wiki/Timestamping_(computing)

   In computing, timestamping refers to the use of an electronic timestamp to provide a temporal order among a set of events. Timestamping techniques are used in a variety of computing fields, from network management and computer security to concurrency control. [1][2] For instance, a heartbeat network uses timestamping to monitor the nodes on a ...

9. Epoch (computing) - Wikipedia

   en.wikipedia.org/wiki/Epoch_(computing)

   Epoch (computing) In computing, an epoch is a fixed date and time used as a reference from which a computer measures system time. Most computer systems determine time as a number representing the seconds removed from a particular arbitrary date and time. For instance, Unix and POSIX measure time as the number of seconds that have passed since ...
