title: How to convert varied "h m s" Excel time formats?
body: <p>I have an excel sheet that  I am importing but I would like some of the data to be converted down to minutes. Though the formats vary from <code>5h 5m 6.64s</code> to <code>6.64s</code> how would i be able to convert this down to only minutes in PHP? (I'm sure <code>DateTime::createFromFormat()</code> wont work as  its range is from 0 to 59.)</p>
  
  <p>Also would be converting down to minutes be an easier format to manipulate and graph within a PHP application or converting it to some time object from a PHP class better?</p>
  
  <p>Keep in mind the data has to be formatted, then imported to a MySQL server then read back to a PHP application to graph for statistical purpose. I'm also using cakePHP framework to build the app. Thanks for any feedback.</p>
