title: How to run a python script at a specific time(s)
body: <p>I'd like to write a simple python script for doing a specific job. I'm getting some time and link information from a web site. </p>
  
  <pre><code>times=
  [
  ('17.04.2011', '06:41:44', 'abc.php?xxx'),
  ('17.04.2011', '07:21:31', 'abc.php?yyy'),
  ('17.04.2011', '07:33:04', 'abc.php?zzz'),
  ('17.04.2011', '07:41:23', 'abc.php?www'),]
  </code></pre>
  
  <p>What is the best way to click these links at the right time? Do I need to calculate the time interval between the current and the one in list and sleep for a while? </p>
  
  <p>I'm really stuck at this point and open to any ideas which could be useful.</p>
