Subject Question about dismax and score boost with date

<fieldType name="tdate" class="solr.TrieDateField" omitNorms="true" 
precisionStep="6" positionIncrementGap="0"/>

<field name="created" type="tdate" multiValued="false" indexed="true" 
stored="false" omitNorms="true"  required="false" 
omitTermFreqAndPositions="true" />

I am using 'created' as the name of the date field.

My dates are being populated as such :

Search handler (solrconfig) :

<requestHandler name="/dismax" class="solr.SearchHandler">
<lst name="defaults">
<str name="defType">dismax</str>
<str name="echoParams">explicit</str>
<str name="tie">0.1</str>
<str name="qf">name0^20000 other ^10000</str>
<str name="pf">name0^20000 other ^10000</str>
<str name="qs">3</str>
<str name="ps">3</str>
<str name="q.alt">*:*</str>


Query :


I am trying to factor in created to the SCORE. (boost) I have tried a 
million ways to do this, no success. I know the dates are populating 
correctly because I can sort by them. Can anyone help me implement date 
boosting with dismax under this scenario???
