Description

• Time stamping is used to prove that data in electronic form existed at a particular time
• It is an increasingly valuable complement to digital signing practices, enabling organizations to record when a digital item (such as a message, document, transaction or piece of software) was signed
• It binds the date and time to data in such a way that data cannot be changed undetectably
• It is based on an accurate time source linked to UTC.
• Time Stamping provides an independent and irrefutable proof of time for transactions, documents and digital signatures. It can also independently prove the exact time a digital signature was applied by the signer so that its validity can be verified in the long-term, even after expiry or revocation of signer’s digital credentials.
