@panemantare,
Can you kindly brief us more about your requirements like the format of date in the source of data (JSON / database) and where would you like to display the date in ‘2017-JUL-24’ format?
Also please share a sample project along with JSON / sample database over Google-Drive or Onedrive so that we can understand the scenario better and help you out.
