FAQ

Q1: What is the difference between a timestamp and a signature time?

The signature time is provided locally by the signer, while the timestamp is provided by a trusted third-party server, making it more credible.

Q2: Can a timestamp be forged?

Timestamps are issued by trusted time servers and cannot be forged.

Q3: What should I do if the timestamp expires?

The timestamp itself does not expire, but the certificate of the timestamp server may need to be updated.

Notes

• A network connection is required to add timestamps.
• Timestamps can be used in conjunction with digital signatures.
• Timestamps prove the status of a document at a specific point in time.
