TimeCert

TimeCert is a web service for timestamping content. This provides evidence by a trusted third-party that something (e.g. a blog post, a document, or a file) existed at a given time. TimeCert records and gives you the timestamp for when someone first referenced a given digital fingerprint.

This module timestamps administrator-selected Drupal content types based on their full URLs, providing evidence that a Drupal page existed at a given time. The module requires PHP 5.2 or newer, and can optionally integrate with Bitcache if installed.

This project was originally developed by Arto Bendiken.
