title: Python display millisecond in h"m's format
body: <p>I have a code that runs trough the facade and sum the duration of the calls that meets criteria, the call duration is on milliseconds.
  Today, the output is on millisecond but I want to display is on the following format hh"mm'ss. </p>
  
  <p>Please advise,
  Nir</p>
  
  <pre><code>    sumout = 0
      x = 0
      y = 0
      for call in facade.getCalls(filter=[Call.setup_start_ts &gt;= beg_ts, Call.setup_start_ts &lt;= end_ts, Call.src_user == user]):
         try:
             sumout += call.call_time
             x += 1
         except TypeError:
             pass;
  
      facade.addResult({
                      'user':user,
                      'total_Outgoing': x,
                      'total_Outgoing_Duration': sumout,})
  </code></pre>
