* @classdesc DateTimeInputWidgets can be used to input a date, a time, or
* a date and time, in either UTC or the user's local timezone.
* Please see the [OOUI documentation on MediaWiki](https://www.mediawiki.org/wiki/OOUI/Widgets/Inputs)
* for more information and examples.
*
* This widget can be used inside a HTML form, such as a OO.ui.FormLayout.
*
* @example
* // Example of a text input widget
* var dateTimeInput = new mw.widgets.datetime.DateTimeInputWidget( {} )
* $( document.body ).append( dateTimeInput.$element );
*
* @class
* @extends OO.ui.InputWidget
* @mixes OO.ui.mixin.IconElement
* @mixes OO.ui.mixin.IndicatorElement
* @mixes OO.ui.mixin.PendingElement
* @mixes OO.ui.mixin.FlaggedElement
*
* @constructor
* @description Create an instance of `mw.widgets.datetime.DateTimeInputWidget`.
* @param {Object} [config] Configuration options
* @param {string} [config.type='datetime'] Whether to act like a 'date', 'time', or 'datetime' input.
* Affects values stored in the relevant `<input>` and the formatting and
* interpretation of values passed to/from
* {@link https://doc.wikimedia.org/oojs-ui/master/js/OO.ui.InputWidget.html#getValue getValue()} and
* {@link https://doc.wikimedia.org/oojs-ui/master/js/OO.ui.InputWidget.html#setValue setValue()}.
* It's up to the user to configure the DateTimeFormatter correctly.
* @param {Object|mw.widgets.datetime.DateTimeFormatter} [config.formatter={}] Configuration options for
* {@link mw.widgets.datetime.ProlepticGregorianDateTimeFormatter} (with 'format' defaulting to
* '@date', '@time', or '@datetime' depending on 'type'), or an
* {@link mw.widgets.datetime.DateTimeFormatter} instance to use.
* @param {Object|null} [config.calendar={}] Configuration options for
* {@link mw.widgets.datetime.CalendarWidget}; note certain settings will be forced based on the
* settings passed to this widget. Set null to disable the calendar.
* @param {boolean} [config.required=false] Whether a value is required.
* @param {boolean} [config.clearable=true] Whether to provide for blanking the value.
* @param {Date|null} [config.value=null] Default value for the widget
* @param {Date|string|null} [config.min=null] Minimum allowed date
* @param {Date|string|null} [config.max=null] Maximum allowed date
