/**
 * Date time control.
 *
 * A base control for creating date time control. Displays a date/time picker
 * based on the jquery-simple-datetimepicker jQuery plugin
 * @see https://github.com/mugifly/jquery-simple-datetimepicker
 *
 * Creating new control in the editor (inside `Widget_Base::_register_controls()`
 * method):
 *
 *    $this->add_control(
 *    	'due_date',
 *    	[
 *    		'label' => __( 'Due Date', 'plugin-domain' ),
 *    		'type' => Controls_Manager::DATE_TIME,
 *    	]
 *    );
 *
 * PHP usage (inside `Widget_Base::render()` method):
 *
 *    $due_date = strtotime( $this->get_settings( 'due_date' ) );
 *    // GMT timezone
 *    // $due_date -= ( get_option( 'gmt_offset' ) * HOUR_IN_SECONDS );
 *    $due_date_in_days = $due_date / DAY_IN_SECONDS;
 *    echo '<p>' . sprintf( __( 'Something will happen in %s days.', 'plugin-domain' ), $due_date_in_days ) . '</p>';
 *
 * JS usage (inside `Widget_Base::_content_template()` method):
 *
 *    <#
 *    var due_date = new Date( settings.due_date ),
 *        now_date = new Date(),
 *        due_date_in_days = Math.floor( ( due_date - now_date ) / 86400000 ); // 86400000 miliseconds in one Day.
 *    #>
 *    <p> Something will happen in {{{ due_date_in_days }}} days. </p>
