title: Use sched module to run at a given time
body: <p>I'm working on a python script that needs to run between two given times. I'm required to use the build in <code>sched</code> module as this script needs to be able to run directly on any machine that has python 2.7 as to reduce configuration time.  (SO CRON IS NOT AN OPTION)</p>
  
  <p>A few variables define the settings for the time to run, here <code>set_timer_start=0600</code> and <code>set_timer_end=0900</code> are written in <code>HHMM</code>. I'm able to stop the script at the right time.</p>
  
  <p>I don't know exactly how <code>sched</code> works (the python doc page doesn't make to much sense to me), but as far as I understand It runs at a date/time (epoch) while I only want it to run at a given time (<code>HHMM</code>).</p>
  
  <p>Can anyone give me an example (or link) on how to use the scheduler and perhaps calculate the next run date/time?</p>
