Listing duration / Time Availability not working correctly

Hi Ihor,
Many thanks for your answer. I am bit puzzled how we have set this up. So, what we want to achieve is:

  • we would like to show the Duration on the Listing front page and on the listing details sheet.
    This works, see Screenshot.
  • and as described previously we would like to achieve that the times (start time and end time ) are displayed correctly.
  • From what I understand with the following snippet we have set the duration automatically to 10 minutes, is this correct?
    Mark Duration the predefined "Duration" field non mandatory
