Can't use ms() function on non-numeric legacy date field

Hi, I had been trying to boost my recent documents, using what is described
here http://wiki.apache.org/solr/FunctionQuery#Date_Boosting

My date field looks like

<fieldType name="date" class="solr.DateField" sortMissingLast="true"
omitNorms="true"/>
<field name="created_at" type="date" indexed="true" stored="true" omitNorms
="true"/>

However, upon trying to do ms(NOW, created_at) it shows the error
Can't use ms() function on non-numeric legacy date field created_at

: Try solr.TrieDateField instead

and note the docs on the "ms" function, from the same wiki page you linked 
to...

>> Arguments may be numerically indexed date fields such as TrieDate 
>> (recommended field type for dates since Solr 1.4), or date math 
>> (examples in SolrQuerySyntax) based on a constant date or NOW.
>> 
>> Things other than these will _not_ work as arguments. For example, you 
>> cannot currently use:
>>  * "classic", non-numerically indexed date fields (i.e. fields backed 
>>     by DateField or LegacyDateField classes) 
>>  * other functions (e.g. map, sum, etc.)
