title: How to get function to run at specyfic time using python and PyQt not using Cron
body: <p>I'm creating RSS app in PyQt and I'm trying to find a good way to program updates. I found this <a href="https://stackoverflow.com/questions/8600161/executing-periodic-actions-in-python">Executing periodic actions in Python</a> but maybe there is Qt specific way to do this things. </p>
  
  <p>I know update period for each feed so I want to run update at specific time(hh:mm).</p>
  
  <p>Making 10 minute loop that will check current time and run a update if its grater than next predicted feed update seems missing the point of knowing specific time to run it.</p>
