just fixed it now, thanks
also needed to change days -> weekdays and add a score to the rule itself.

here's the complete fragment

     <rsc_defaults>
       <meta_attributes id="core-hours" score="2">
	 <rule id="core-hour-rule" score="1">
           <date_expression id="nine-to-five-Mon-to-Fri" operation="date_spec">
             <date_spec id="nine-to-five-Mon-to-Fri-spec" hours="9-17"
weekdays="1-5"/>
           </date_expression>
	 </rule>
	 <nvpair id="core-stickiness" name="resource-stickiness" value="INFINITY"/>
       </meta_attributes>
       <meta_attributes id="after-hours" score="1" >
	 <nvpair id="after-stickiness" name="resource-stickiness" value="0"/>
       </meta_attributes>
     </rsc_defaults>

Yes, but only for the node its running on.
