Feature Description

Created a form with input field with format as date-time

            "startDateTime": {
              "title": "Start Date",
              "description": "Start date",
              "type": "string",
              "format": "date-time"
            },

Selected date from the popup widget:

The date was correctly saved in the Homebridge UI config:

            "startDateTime": "2024-11-11T19:23:00Z",

Given that Homebridge has an international following, I would like to be able to display the locale format expected for the date-time (this would be the user's/browser's locale). Something similar to this photoshopped image

Using the calendar widget, the selected the date-time is displayed in the field in the user's locale.
