/**
* Expands a datetime element type into date and/or time elements.
*
* All form elements are designed to have sane defaults so any or all can be
* omitted. Both the date and time components are configurable so they can be
* output as HTML5 datetime elements or not, as desired.
*
* Examples of possible configurations include:
* HTML5 date and time:
* #date_date_element = 'date';
* #date_time_element = 'time';
* HTML5 datetime:
* #date_date_element = 'datetime';
* #date_time_element = 'none';
* HTML5 time only:
* #date_date_element = 'none';
* #date_time_element = 'time'
* Non-HTML5:
* #date_date_element = 'text';
* #date_time_element = 'text';
*
* Required settings:
* - #default_value: A DrupalDateTime object, adjusted to the proper local
* timezone. Converting a date stored in the database from UTC to the local
* zone and converting it back to UTC before storing it is not handled here.
* This element accepts a date as the default value, and then converts the
* user input strings back into a new date object on submission. No timezone
* adjustment is performed.
* Optional properties include:
* - #date_date_format: A date format string that describes the format that
* should be displayed to the end user for the date. When using HTML5
* elements the format MUST use the appropriate HTML5 format for that
* element, no other format will work. See the
* DateFormatterInterface::format() function for a list of the possible
* formats and HTML5 standards for the HTML5 requirements. Defaults to the
* right HTML5 format for the chosen element if an HTML5 element is used,
* otherwise defaults to DateFormat::load('html_date')->getPattern().
* - #date_date_element: The date element. Options are:
* - datetime: Use the HTML5 datetime element type.
* - datetime-local: Use the HTML5 datetime-local element type.
* - date: Use the HTML5 date element type.
* - text: No HTML5 element, use a normal text field.
* - none: Do not display a date element.
* - #date_date_callbacks: Array of optional callbacks for the date element.
* - #date_time_element: The time element. Options are:
* - time: Use an HTML5 time element type.
* - text: No HTML5 element, use a normal text field.
* - none: Do not display a time element.
* - #date_time_format: A date format string that describes the format that
* should be displayed to the end user for the time. When using HTML5
* elements the format MUST use the appropriate HTML5 format for that
* element, no other format will work. See the
* DateFormatterInterface::format() function for a list of the possible
* formats and HTML5 standards for the HTML5 requirements. Defaults to the
* right HTML5 format for the chosen element if an HTML5 element is used,
* otherwise defaults to DateFormat::load('html_time')->getPattern().
* - #date_time_callbacks: An array of optional callbacks for the time
* element. Can be used to add a jQuery timepicker or an 'All day' checkbox.
* - #date_year_range: A description of the range of years to allow, like
* '1900:2050', '-3:+3' or '2000:+3', where the first value describes the
* earliest year and the second the latest year in the range. A year
* in either position means that specific year. A +/- value describes a
* dynamic value that is that many years earlier or later than the current
* year at the time the form is displayed. Used in HTML5 min/max date
* settings. Defaults to '1900:2050'.
* - #date_increment: The interval (step) to use when incrementing or
* decrementing time, in seconds. For example, if this value is set to 30,
* time increases (or decreases) in steps of 30 seconds (00:00:00,
* 00:00:30, 00:01:00, and so on.) If this value is a multiple of 60, the
* "seconds"-component will not be shown in the input. Used for HTML5 step
* values. Defaults to 1 to show every second.
* - #date_timezone: The Time Zone Identifier (TZID) to use when displaying
* or interpreting dates, i.e: 'Asia/Kolkata'. Defaults to the value
* returned by date_default_timezone_get().
*
* Example usage:
* @code
* $form = array(
* '#type' => 'datetime',
* '#default_value' => new DrupalDateTime('2000-01-01 00:00:00'),
* '#date_date_element' => 'date',
* '#date_time_element' => 'none',
* '#date_year_range' => '2010:+3',
* '#date_timezone' => 'Asia/Kolkata',
* );
* @endcode
*
* @param array $element
* The form element whose value is being processed.
* @param \Drupal\Core\Form\FormStateInterface $form_state
* The current state of the form.
* @param array $complete_form
* The complete form structure.
*
* @return array
* The form element whose value has been processed.
*
* @see \Drupal\Core\Datetime\DateFormatterInterface::format()
