Drupal Gotchya: Cache_get() Returns Expired Items

function custom_monkey_grip_data() {
  // Return the cached data
  $cache = cache_get('custom:monkey_grip');
  if (!$cache) {
    // Some expensive processing to build the data.
    $data = complicated_recursion_and_loops_on_lots_of_data();
   
    // Cache the data and rebuild it every hour
    $expire = time() + (60 * 60);
    cache_set('custom:monkey_grip', $data, 'cache', $expire);
  }
  else {
    $data = $cache->data;
  }
  return $data;
}
?>
