How to convert to Time Duration
<p>The time duration is being described using four sets of double digits numbers separated with columns such as <code>00:02:01:16</code>.
I know that this represents a time interval or a time duration.
I would like to translate it to a single number that represents a time duration in a more common form such as "120 seconds" or "12 minutes". What approach should be taken here?</p>

<pre><code>", ".join((a+b for a,b in zip(time_s.split(":")," hour(s), min(s), second(s), ms".split(","))))
</code></pre>
