This may be a stupid question, but are you running with the latest code or an older version of Drools?

Hi All,
 
I am trying to implement a timer in a rule so that it executes every 15min i have the following code:
 
rule " When average temperature is greater than 19 turn on fans"
 
   timer(int:0 15m)
 
        when
                 $t : Temperature($room : room)
                 $fan : Fan( room == $room )
        then
                "i need to implement this yet
 
end
 
I am getting on the timer: "[ERR 101]Line 61:0 no viable alternative at input 'timer' in rule ......
I read example 2.12. Example timer attribute uses from https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-introduction/html/ch02.html
and this is how it says to implement a timer.
 
Any help is greatly appreciated.
 
Kind regards,
James.
