Information technology. Security techniques. Time-stamping services - Framework subscription-only The external application of concreteA time stamping service provides evidence that a data item existed before a certain point in time. Time stamp services produce time stamp tokens, which are data structures containing a verifiable cryptographic binding between a data item's representation and a time value. This part of ISO IEC 18014 defines time stamping mechanisms that produce independent tokens, which can be verified one by one.
