/// Represents a date without time information (e.g. a birthday) for transmission from and to a REST API
///
/// This type is used as a representation for openapi specs `date` format which does not contain
/// time information as opposed to the `date-time` format. Although it internally uses `Date` for
/// (de-)serialization as well the generator needs to be able to distinguish between the two formats.
/// - note: As `Date` is agnostic to timezones (and calendars), timezone information is needed to be able to add
/// an appropriate padding in order to transform to GMT+0 which is the assumed timezone in ISO 8601.
/// When decoding, GMT+0 can be assumed (again: ISO8601) so there is no padding necessary and wrappedDate
/// can be used safely.
