title: DateTime in Hyperledger
body: <p>I want to enter the participant's Date of Birth as input when i go to Test tab and click <code>+ Create New Participant</code> (JSON file). </p>
  
  <p>But if I use the <code>DateTime</code> datatype as given in <a href="https://hyperledger.github.io/composer/latest/reference/cto_language" rel="nofollow noreferrer">github documentation for Hyperledger Composer Modeling Language</a>, the <strong>current</strong> date and time is auto inserted which I don't want. How can I do it?</p>
