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: 2021-01-16T02:53:46.141953+01:00
formatted currentDateTime: 16.01.2021 01:53
