title: Can we update a datapoint in Graphite using same timestamp?
body: <p>Let's understand my usecase.</p>
  
  <p>I want to store some point data along with time-series data in Graphite. I have some metric say <strong><em>user.12345.lastVisitedTimeInMs</em></strong> and I want to update it each time the user visited our site.
  So, this information is not a time-series data but a point data.</p>
  
  <p>Is it possible in Graphite to update a metric's value instead of putting another value with a new timestamp?</p>
