When we was signing document, we was using time from our time. For more
security we can use Time Stamp server.
"Trusted timestamping is the process of securely keeping track of the creation
and modification time of a document. Security here means that no one — not even
the owner of the document — should be able to change it once it has been
recorded provided that the timestamper's integrity is never compromised."(wiki)
