title: PowerPivot - Changed, incorrect date formatting when using data as column filter
body: <p>I am using the Excel Add-In PowerPivot to draw a list of values from a <strong>Postgre-SQL</strong> database. The first column is a date with format <code>(m)m/(d)d/yyyy</code>. Whenever I create a pivot table based on the raw data and use the date as row name, the <strong>date</strong> is displayed in the German format (my Excel is a German version, however regional settings are set to EN).</p>
  
  <p>I need it to stay in its original format. I cannot use an additional calculated column for that. What possibilities are there to resolve this issue?</p>
