What is a Trusted Timestamp?
A trusted timestamp is a timestamp issued by a Trusted Timestamping Authority (TSA) and meet RFC 3161, RFC 5816 and ETSI requirements. A qualified timestamp is issued by an eIDAS Qualified Trust Service Provider. Qualified electronic timestamps enjoy, all over the EU, the presumption of the accuracy of the date and the time it indicates and the integrity of the data to which the date and time are linked and assure non-repudiation of data and documents.
A qualified timestamp provides cryptographic proof that a data object existed at the UTC time shown within the timestamp. The time is provided from multiple NTP (Network Time Protocol) Servers according to the EU legislation.
The TSA service is included as part of commercial managed PKI services

F.A.Q
1 What is the eIDAS Regulation?
Regulation (EU) No 910/2014 (the eIDAS Regulation) went into force on 1 July, 2016 having 'direct effect'-in other words, being mandatory and wholly adopted in all EU member states, with precedent over any conflicting national laws. It replaces the eSignature Directive (1999/93/EC) and establishes an EU-wide legal framework for electronic signatures and a range of newly defined electronic "trust services".
2 What is an EU Qualified Timestamp Service?
An electronic timestamp is data in electronic form which binds other data in electronic form to a particular time establishing evidence that the latter data existed at that time. As part of the eIDAS Regulation, a timestamp can be qualified. Following stricter requirements laid down in eIDAS, a qualified electronic timestamp enjoys the presumption of the accuracy of the date and the time it indicates and the integrity of the data (e.g. signed document) to which the date and time are bound. Zipper Services is a provider of qualified timestamping services in accordance with the provisions of the European Regulation 910/2014 (eIDAS).
