title: Celery - schedule periodic tasks starting at a specific time
body: <p>What is the best way to schedule a periodic task starting at specific datetime?</p>
  
  <p>(I'm not using cron for this considering I've the need to schedule about a hundred remote rsyncs, 
  where I compute the remote vs local offset and would need to rsync each path the <strong>second</strong> the logs are generated in each host.)</p>
  
  <p>By my understanding the celery.task.schedules crontab class only allows specifying hour, minute, day of week.
  The most useful tip I've found so far was <a href="https://stackoverflow.com/questions/1990531/how-can-i-schedule-a-task-to-execute-at-a-specific-time-using-celery/1990599#1990599">this answer by nosklo</a>.</p>
  
  <p>Is this the best solution?
  Am I using the wrong tool for the job?</p>
