title: How to use Jobqueue in Python-telegram-bot
body: <p>I have able to make a bot very easily by reading the <a href="https://python-telegram-bot.readthedocs.io/en/stable/telegram.ext.jobqueue.html" rel="noreferrer">docs</a> but Jobqueue is not working as per it is written. The <code>run_daily</code> method uses a <code>datetime.time</code> object to send the message at a particular time but this code neither does its job of sending a message nor shows any errors. It just keeps running</p>
  
  <pre><code>    import datetime
      from telegram import bot
      from telegram.ext import Updater
      def callback_minute(bot, job):
          bot.send_message(chat_id=475838704, text='PlEaSe wOrK!')
  
      def main():
          updater = Updater()
          bot = updater.bot
          job = updater.job_queue
  
          dispatcher = updater.dispatcher
  
          job.run_daily(callback_minute, time=datetime.time(6,33,00))
  
          updater.start_polling()
          updater.idle()
  
      if __name__ == '__main__':
          main()
  </code></pre>
