        {
            "type": "TextBlock",
            "text": "Your package will arrive on {{DATE(2017-02-14T06:00:00Z, SHORT)}} at {{TIME(2017-02-14T06:00:00Z)}}",
            "wrap": true
        }
    ]
}

Answer 1

This is byDesign Behavior.
We use the localization date/time format of the language selected in the Teams desktop app, not the local desktop. This is by design.

If the developer switches the language of their app, then the date and time format should be aligned with the country of origin.
