title: Method to run only once a day
body: <p>I have to make request to an API to get access token. It expires in a day i.e. 86400 secs or 24 hours. I need to get a new access token once a new day is started.</p>
  
  <p>Below is my API access code:</p>
  
  <pre><code>def get_access_token():
      logging.info('Started to get access token')
      response = requests.post(settings.URL, data=params).json()
      logging.info('Fetched Access token')
      return response
  </code></pre>
  
  <p>I need to make sure only above method get_access_token runs once at first hour everyday. My whole job runs every hour using blockingscheduler. Only above piece of code needs to run once at first hour everyday.</p>
  
  <p>Please let me know how it can be achieved ?</p>
