Display 24H time

In a form I set the appearance of a DateTime attribute to a 'Time' format. However, this is a AM/PM time appearance. Is there also a way to show a 24H clock time format?

Use the proper localization or use date format: custom. And then take a look at Simple date formats


Hey, I want to elaborate on this answer as I’m also stuck on this question.

it's simple actually,  

  1. go to your attribute (date and time)
  1. double click on the attribute and inside this you will get date format.
  2. from this date format select custom and click on edit button of custom date format
  3. inside you will get list of format you can add it by double clicking on it.
