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.
Generates a more readable output for timestamps in the format YYYYMMDDHHMMSS – as returned by the {{REVISIONTIMESTAMP}} magic word. For example, {{ FRTS | 20230501215438 }} is output as "2023-05-01 21:54:38".
