title: Neo4j: How could I add a date created (or modified) on every node's properties?
body: <p>I created a web application that use a Neo4j database and I need to know when a property is created or modified by an user.
  Do you have any advices for me?
  I thought to modify every property in an array where there will be the real value of property and a timestamp value (but I don't know how to do).</p>
