Re: [rules-users] Date arithmetic in “when” session

[sridhar123]

Ok, finally I am able to solve this puzzle:

	$req : LowFareRequest(
    			$reqTime : requestedDeparture.time)
    	$itr : AirItinerary( discarded == false )
     	$flight : Flight( $depart : departure.time)
       eval (((Long)$depart).longValue() * 2  < 
((Long)$reqTime).longValue() &&  ((Long)$depart).longValue() * 4  > 
((Long)$reqTime).longValue())
   
Thank you all who helped out.
