Changes
=== CreationTimeStamp ===
Saves the date and time when an object is created.
The CreationTimeStamp (cts) is set exactly once and in that moment when a new Ubikle is instantiated in the working memory. This time stamp will never be changed by UBIK. This timestamp does not denote when the Ubikle was written to the database eventually.
