Print Difference Between Time in Ms
<p>I am reading a log file in my <code>python</code> script, and I have got a list of tuples of <code>startTimes</code> and <code>endTimes</code> - </p>

<pre><code>('[19:49:40:680]', '[19:49:49:128]')
('[11:29:10:837]', '[11:29:15:698]')
('[11:30:18:291]', '[11:30:21:025]')
('[11:37:44:293]', '[11:38:02:008]')
('[11:39:14:897]', '[11:39:21:572]')
('[11:42:19:968]', '[11:42:22:036]')
('[11:43:18:887]', '[11:43:19:633]')
('[11:44:26:533]', '[11:49:29:274]')
('[11:55:03:974]', '[11:55:06:372]')
('[11:56:14:096]', '[11:56:14:493]')
('[11:57:08:372]', '[11:57:08:767]')
('[11:59:26:201]', '[11:59:27:438]')
</code></pre>

<p>How can I take a difference of the times in milliseconds?</p>
