FAQ
What is the difference between a timestamp and a signing time?
- A signing time is usually provided by the signer’s local environment.
- A timestamp time is provided by a trusted third-party server.
- When you need to prove the state of a document at a specific time, review the timestamp information first.
Can a timestamp be forged?
- A timestamp is issued by a trusted timestamp server.
- Review the timestamp server and timestamp status when checking it.
- If the status is normal, it can serve as an important reference for verifying document time information.
What should I do if a timestamp appears expired?
- The timestamp itself does not expire.
- If related certificates need renewal, review the certificate status of the timestamp server.
- If validation behaves unexpectedly, check the server-related settings or the current validation result again.
