-     * - `name` - Set the input name.
-     * - `options` - An array of options.
-     * - `disabled` - Either true or an array of options to disable.
-     *    When true, the select element will be disabled.
-     * - `val` - Either a string or an array of options to mark as selected.
-     * - `empty` - Set to true to add an empty option at the top of the
-     *   option elements. Set to a string to define the display text of the
-     *   empty option. If an array is used the key will set the value of the empty
-     *   option while, the value will set the display text.
-     * - `escape` - Set to false to disable HTML escaping.
-     *
-     * ### Options format
-     *
-     * The options option can take a variety of data format depending on
-     * the complexity of HTML you want generated.
-     *
-     * You can generate simple options using a basic associative array:
-     *
-     * ```
-     * 'options' => ['elk' => 'Elk', 'beaver' => 'Beaver']
-     * ```
-     *
-     * If you need to define additional attributes on your option elements
-     * you can use the complex form for options:
-     *
-     * ```
-     * 'options' => [
-     *   ['value' => 'elk', 'text' => 'Elk', 'data-foo' => 'bar'],
-     * ]
-     * ```
-     *
-     * This form **requires** that both the `value` and `text` keys be defined.
-     * If either is not set options will not be generated correctly.
-     *
-     * If you need to define option groups you can do those using nested arrays:
-     *
-     * ```
-     * 'options' => [
-     *  'Mammals' => [
-     *    'elk' => 'Elk',
-     *    'beaver' => 'Beaver'
-     *  ]
-     * ]
-     * ```
-     *
-     * And finally, if you need to put attributes on your optgroup elements you
-     * can do that with a more complex nested array form:
-     *
-     * ```
-     * 'options' => [
-     *   [
-     *     'text' => 'Mammals',
-     *     'data-id' => 1,
-     *     'options' => [
-     *       'elk' => 'Elk',
-     *       'beaver' => 'Beaver'
-     *     ]
-     *  ],
-     * ]
-     * ```
-     *
-     * You are free to mix each of the forms in the same option set, and
-     * nest complex types as required.
+     * Render a date / time form widget.
+     *
+     * Data supports the following keys:
+     *
+     * - `name` The name attribute.
+     * - `val` The value attribute.
+     * - `escape` Set to false to disable escaping on all attributes.
+     * - `type` A valid HTML date/time input type. Defaults to "datetime-local".
+     * - `timezone` The timezone the input value should be converted to.
+     * - `step` The "step" attribute. Defaults to `1` for "time" and "datetime-local" type inputs.
+     *   You can set it to `null` or `false` to prevent explicit step attribute being added in HTML.
+     * - `format` A `date()` function compatible datetime format string.
+     *   By default, the widget will use a suitable format based on the input type and
+     *   database type for the context. If an explicit format is provided, then no
+     *   default value will be set for the `step` attribute, and it needs to be
+     *   explicitly set if required.
+     *
+     * All other keys will be converted into HTML attributes.
