title: liquid transform of string value to date format
body: <p>I have just started using liquid mapping in Logic apps for transforming json data to text. I have to convert date in a specific format.
  In the json data, I have date value as <code>20181230T000000.000 GMT</code> and i want to transform the date in "MMddyy" format.</p>
  
  <p>I had used <code>{{"now" | Date: "MMddyy"}}</code>
  for transforming current date to specific format.
  But when i am using the same syntax of transforming current date in specific format it works as in following answer 
  <a href="https://stackoverflow.com/questions/21056965/date-math-manipulation-in-liquid-template-filter?rq=1">Date Math / Manipulation in Liquid Template Filter</a></p>
  
  <p>But when the same syntax I am trying to utilize while picking up data from JSON, it's not working. what could be possibly wrong?</p>
  
  <p>Json data example:</p>
  
  <pre><code>{
      "ItemSerialNumber" : "ItemSerialNumber",
      "ExchangeOrderNo" : "ExchangeOrderNo",
      "ShipDate" : "20181230T000000.000 GMT"
  }
  </code></pre>
  
  <p>transformation syntax tried : <code>{{content.ShipDate | Date: "MMddyy"}}</code></p>
  
  <p>but it didn't worked and output came <code>20181230T000000.000 GMT</code></p>
