This site creates and validates notarized/certified timestamps for character based content. The site was designed to be a back-end service to blog/cms software. When normal blog content is created, an easily modifiable timestamp is created. It is impossible to tell with any real certainity whether or not the content was created at that time. A certified timestamp guarantees the content was created on the timestamp indicated.
