hook_cron_queue_info doesn't run
You have to return $queues in your hook_cron_queue_info..

function timesdb_cron_queue_info() {
  watchdog("timesdb","timesdb_cron_queue_info called");
  $queues['alltimesynch'] = array (
    'worker callback' =&gt; 'timesdb_import_alltime_start',
  );
  return $queues;
}
