Evidence of the existence of a document at a specific time
The electronic signature identifies the originator of the document, while the time stamp records exactly when the document was created or signed. This is why these elements are commonly used together.
A qualified time stamp provides credible and independent evidence that will stand up to legal scrutiny. It is fully compliant with Czech legislation and the European eIDAS Regulation. Such a stamp contains:
- a unique serial number,
a time stamp with an accuracy of 500 ms,
a hash of the document obtained from the stamp request,
the electronic seal of the TSU time server that issued the stamp.
