I wouldn't say it this way.  

RDF is atemporal, so using RDF in domains where truth varies over time
requires some accommodation.  There are a number of such accommodations,
including some of those that are used for the same purpose in databases.

Whether anything needs to be done on this at the moment is the question
that needs to be answered.  My vote would be a firm "NO".
