twig: Simple format date and time

Task: Display formatted time from http://worldtimeapi.org/api/timezone/Europe/Berlin.
If you want to set the language (e. g. name of weekdays and month) and the timezone: see here
See how this works:
  1. Template: 
    currentDateTime: {{datetime }}
    
formatted currentDateTime: {{datetime| date("d.m.Y H:i") }}
    Remember ID of this Template, e.g. TEMPLATE_ID
  2. Shortcode:
    [jsoncontentimporterpro url=http://worldtimeapi.org/api/timezone/Europe/Berlin id=TEMPLATE_ID]
In Action:
currentDateTime:2021-10-18T11:45:23.133471+02:00
formatted currentDateTime:18.10.2021 09:45
