title: Helper class in ABAP to convert to Odata primitive types
body: <p>Is there any helper class in ABAP which I could use to convert ABAP data type of  Date time format to that of Odata type ? I am creating a JSON payload natively in ABAP to post to a http REST API and the service expects the date to be in edm.datetimeoffset format . I was wondering if there is way to convert a date time stamp to that format so I could convert and send it out as a string.  </p>
