APAR status

• Closed as program error.

Error description

• Environment: Windows XP
  Rational Business Developer 7.5.1.6
  Description:
  The Date calculations that involve values being assigned from a
  String are working correctly, but if the value is coming from
  CurrentDate or TextField.text, the calculation does not work
  correctly.
  
  Example:
  RUIhandler {initialUI = [],onConstructionFunction
  = initialization, cssFile='css/test.css'}
  
      function calculateDate(dateD date in)
  
          SysLib.writeStdout('date: ' + dateD);
  
          dateD -= 0;
  
          SysLib.writeStdout('-0 days: ' + dateD);
  
          dateD -= 1;
  
          SysLib.writeStdout('-1 days: ' + dateD);
  
      end
  
      function initialization()
  
          dateD date = currentDate();
  
          calculateDate(dateD);
  
          dateS String = currentDate();
  
          dateD = dateS;
  
          calculateDate(dateD);
  
      end
  
  end
  
  // Result:
  
  //date: 10/14/2010
  
  //-0 days: 10/15/2010
  
  //-1 days: 10/14/2010
  
  //date: 10/14/2010
  
  //-0 days: 10/14/2010
  
  //-1 days: 10/13/2010

  the calculation may be incorrect by one day, depending on
  the current time and time zone.
