title: Where is GetTickCount after Delphi 6?
body: <p>I am trying to migrate from Delphi 6 to Delphi 2010, but I cannot find the <code>GetTickCount</code> function in Delphi 2010. I have <code>IdGlobal</code>, <code>SysUtils</code>, and <code>DateUtils</code> in my uses clause.</p>
  
  <pre><code>var
    RefreshTick : Cardinal;
  begin
    RefreshTick := GetTickCount;
  end;
  </code></pre>
  
  <p>It gives me an error:</p>
  
  <blockquote>
    <p>Undeclared identifier : GetTickCount</p>
  </blockquote>
  
  <p>What's an alternative to this?</p>
