JSCalendar/CCK/Date modules creating ISO 8601 error

I have installed the latest versions of JSCalendar, CCK and the date modules, and no matter what I do, whenever a date CCK field is submitted using dates chosen from JSCalendar, it comes up with this error:

(name of field) must be entered in ISO 8601 format (YYYY-MM-DDThh:mm:ss).

I get this error for each date field using JSCalendar. Here's the code I'm using to attach JSCalendar to the date fields:

<?php
function date_form_alter($form_id, &$form) {
  if (isset($form['type']) && $form['type']['#value'] .'_node_form' == $form_id) { 
    //set this to the type of content you want to publish on
    if ($form['type']['#value'] == 'content-employment_opportunity') {
      $form['field_expiration_date'][0]['value']['#attributes'] = array('class' => 'jscalendar');
      $form['field_deadline_for_application'][0]['value']['#attributes'] = array('class' => 'jscalendar');
	$form['field_publish_date'][0]['value']['#attributes'] = array('class' => 'jscalendar');
      // Use only year, month, and day in textfield.
      $form['#jscalendar_ifFormat'] = '%Y-%m-%d';
      // Don't show time.
      $form['#jscalendar_showsTime'] = 'false';
    }
  }
}
?>

I figure that I am doing something wrong, but I cannot figure out what. Any help would be very appreciated.
