How would I convert a number in a certain format to an integer?
<p>I have a funciton which returns the hours of a timestamp using 24 hour time</p>

<p>e.g.</p>

<p>03, 04, 12, 15</p>

<p>I want to be able to remove the 0 from the integer so instead of 03 I get 3..</p>

<p>Is there a quick function to do this or do I have to use a switch statement?</p>
