The Time Stamping Authority (TS@) offers time stamping services synchronised with the official time, including time stamp issue and validation. It is available to all public administrations, irrespective of the level of government: General Administration, Autonomous Communities, Provincial or Local Governments.
TS@ ensures certification by a trustworthy third party of the date and time of any transaction or procedure by electronic means. Issuing a time stamp on a document gives evidence that the document exists at a given time.
The validation interface can be used to validate previously issued time stamps or know whether a time stamp is valid on the current date. The restamping interface enables users to restamp previously issued time stamps.
