title: strtotime not working with mm-dd-yyyy
body: <p>I have a script which is fed dates in numerous different formats.</p>
  
  <p>I want to save these dates as timestamps so they can easily be manipulated/ordered.</p>
  
  <p>When i try an convert a mm-dd-yyyy type date to a timestamp, it fails.</p>
  
  <p>When the script runs, it does not know what format it will be fed, and as such this cannot be specified. Near all other formats of date seem to be converted fine.</p>
  
  <p>Could anyone advise how to fix this, or alternatively an alternative way that all date formats can be converted to an orderable, consistent format that can be manipulated?</p>
  
  <p>Many Thanks</p>
