Subtracting seconds from int with no formatting
<p>I have an array of different times that looks like this:</p>

<pre><code>20120628061533.0, 20120628064851.0, 20120628064853.0, 20120628064920.0, 20120628064929.0
</code></pre>

<p>what I want to do is subtract 10 seconds 30 seconds and one minute from the times but the problem I am facing is that I can't simply just subtract 10 or 30 or 60 because then the numbers would no longer be in time format(ie. the last two digits can be greater than 60)</p>

<p>Is there anyway to do this easily?</p>
