  * Elgg date input
  * Displays a text field with a popup date picker.
  *
- * @package Elgg
- * @subpackage Core
+ * The elgg.ui JavaScript library initializes the jQueryUI datepicker based
+ * on the CSS class .elgg-input-date. It uses the ISO 8601 standard for date
+ * representation: yyyy-mm-dd.
  *
- * @uses $vars['value'] The current value, if any (as a unix timestamp)
+ * Unix timestamps are supported by setting the 'timestamp' parameter to true.
+ * The date is still displayed to the user in a text format but is submitted as
+ * a unix timestamp in seconds.
  *
+ * @uses $vars['value']     The current value, if any (as a unix timestamp)
+ * @uses $vars['class']     Additional CSS class
+ * @uses $vars['timestamp'] Store as a Unix timestamp in seconds. Default = false
+ *                          Note: you cannot use an id with the timestamp option.
