Elasticsearch date format mapping
<p>So, i have the following date format which i want to import in elasticsearch as a date field : </p>

<pre><code>2015-01-12T03:00:00
</code></pre>

<p>Unfortunately, this format is not recognised by elasticsearch with the following mapping : </p>

<pre><code>{
    "mappings": {
      "veenendaal_type_new": {
        "properties": {

          }
        }
      }
    }
  }  
</code></pre>

<p>Elasticsearch returns this error : </p>

<pre><code>MapperParsingException[failed to parse [Tijdsperiode]]; nested: IllegalArgumentException[Invalid format: "2015-01-12T03:00:00" is malformed at "T03:00:00"];
</code></pre>

<p>My question is, how can i make this format <strong>(2015-01-12T03:00:00)</strong> valid for elasticsearch? </p>
