<div style="margin-top: 5pt; margin-bottom: 5pt; ">I'm wanting to use the date-effective and date-expiry rule metadata to add date specific rule variants within my app. To test these I was planning on using the pseudo clock and setting the expected date prior
to executing the rules within a StatelessKnowledgeSession. I can set the clock easily enough, but can't understand why the getSessionClock() method is missing? It's on the StatefulKnowledgeSession, but not on the Stateless. </div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">I'm initialising the session like this:<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">SessionConfiguration sessionConfiguration = new SessionConfiguration();<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">sessionConfiguration.setClockType( ClockType.PSEUDO_CLOCK );<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">StatelessKnowledgeSession session = _testKnowledgeBase.newStatelessKnowledgeSession(sessionConfiguration); </div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">The only thing I could think of to set the pseudo clock was to write a command something like:<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">private static class SetPseudoClockCommand implements org.drools.process.command.Command<Boolean> {<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">public Boolean execute(ReteooWorkingMemory session) {<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">// Set the clock to the current date<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">pseudoSessionClock.advanceTime(new DateTime().getMillis(), TimeUnit.MILLISECONDS);<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">// Add a couple of days<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">pseudoSessionClock.advanceTime(2, TimeUnit.DAYS); </div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">return true;<font size="3"> </font></div>

<div style="margin-top: 5pt; margin-bottom: 5pt; ">}<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">But this doesn't appear to take any effect whilst rules are running.<font size="3"> </font></div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">Is there another way to get programmatic access to the session clock, or some better way of changing the underlying date prior to rule execution? </div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">Ben. </div>
