> 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)
