This allows you to display the date and/or time, can be heavily configured using Intl.DateTimeFormat.

Formatting is locale aware and will present your date in the regional format you expect, for example, 9/16/22, 3:03 PM for locale en and 16.09.22, 15:03 for de. You can also specify a locale just for the datetime widget with the locale option (see below).

- datetime:
    text_size: xl
    format:
      timeStyle: short

Any options passed to format are passed directly to Intl.DateTimeFormat, please reference the MDN documentation for all available options.

Valid text sizes are 4xl, 3xl, 2xl, xl, md, sm, xs.
