A timestamp represents data in electronic format that links other data in electronic format to a particular time, establishing evidence that the latter existed at that time. A qualified timestamp is issued by a qualified trusted service provider. It is used, for example, to ensure that electronic data, such as an electronic signature, exists at a certain point in time.
A qualified electronic time stamp benefits in the event of a dispute from the presumption of the correctness of the date and time it indicates and the integrity of the data to which the given date and time is reported.
A qualified electronic time mark issued in a EU Member State is recognized as a qualified electronic time stamp in all Member States.
