title: Querying Hibernate Envers revision by revision date
body: <p>I have started using Hibernate Envers for audit logging business objects.
  I have read the documentation and from all the examples i have seen, querying is done by revision number.</p>
  
  <p>I would like to query by revision date, i.e. get all the rows of an audited entity the happened at a specific date or date range.
  I such a thing possible? </p>
  
  <p>My revinfo table holds a timestamp so i know the data is there.</p>
