Calculate Hours Between 2 Times
<p>I need a way of calculating how many hours are between 2 times.</p>

<p>Wouldn't be a problem if I was using <strong>unix timestamp</strong> but I need to work for a "24 hour clock".</p>

<p><em>For example, work out how many hours are between:</em></p>

<p><strong>01:00 and 16:30</strong></p>

<p>Any thoughtd would be great, Thanks!</p>
