title: drools cep current date
body: <p>I am using drools 6 + CEP (fusion) and I need to check that certain event happened 10 min before the current time the rule is checked. For this, I made the following approach:</p>
  
  <pre><code>rule "Before rule test"
  when
      $fall : Fall()
      $current : Date(this after[10m] $fall)
  then
      System.out.println("Fall older than 10m at least");
  </code></pre>
  
  <p>end</p>
  
  <p>This is working correctly if I insert a fact <code>new Date()</code> every run, so I am wondering if I there is any object to do something like this:</p>
  
  <pre><code>rule "Before rule test"
  when
      $fall : Fall(this before[10m] drools.currentDate)
  then
      System.out.println("Fall older than 10m at least");
  </code></pre>
  
  <p>end</p>
  
  <p>Thank you very much!</p>
