title: Difference between 2 dates in Delphi 5
body: <p>I want to be able to find the difference in seconds between two TDateTime variables in Delphi 5. In the later versions of delphi there are helper functions <a href="http://docwiki.embarcadero.com/Libraries/XE5/en/System.DateUtils.SecondsBetween" rel="nofollow">SecondsBetween</a> to do this. Is there a better way to do this other than rolling my own (Finding the difference of the two variables as a double then converting them to seconds)?</p>
  
  <p>Thanks.</p>
