title: HPQC ALM : what is the format for Date field in REST based query
body: <p>I am trying to use REST call to HP QC ALM12. It works so far but hit a problem when trying to query based on a Date field. Wondering what's the correct syntax to specify a Date query. For example, for the field 'creation-time', how do I filter result within a period ? I have tried these but got HTTP 500 error:</p>
  
  <p>{creation-time[>= '2015-01-01' AND &lt;= '2015-06-01']}
  {creation-time[>= '2015-01-01T00:00:00.000Z']</p>
  
  <p>thanks for any help.</p>
