 * Log of what is going on in the project.

 * We log here what is going on. It is important that creation_dtime
 * must be set at the *real* date time of the creation of the object,
 * which is not necessarily the date of the insert in the
 * database. For example, code can be created 3 days ago and committed
 * in the main repository.
 *
 * The public_dtime is the date at which the information is being made
 * public and here that would be the commit date time of the code.
