Problem summary

• Problem Description:
  Under some circumstances the result of calculateBusinessDate
  returns a wrong date or time.
  In the customer scenario calculateBusinessDate returns a sunday,
  although the workschedule is set to "9AM-5PM M-F".
  If the timezone of the workschedule and the original date
  differs, the propability of wrong result increases.
  
  Problem Summary:
  The larger the time difference between the workschedule and the
  original date the larger is the probability of an
  incorrect business date calculation.
  e.g.
  Asia/Manila is 6 hours before Europe/Berlin.  A business date
  calculation of minus 1 hour with
  an original date of     "Fri Sep 07 2012 03:00:00" in
  Europe/Berlin
  and a workschedule of   "9AM-5PM M-F" in Asia/Manila
  should return
  a business date of      "Thu Sep 06 2012 10:00:00" in
  Europe/Berlin,
  but a business date calculation of minus 1 hour with
  an original date of     "Fri Sep 07 2012 04:00:00" in
  Europe/Berlin
  and a workschedule of   "9AM-5PM M-F" in Asia/Manila
  should return
  a business date of      "Fri Sep 07 2012 03:00:00" in
  Europe/Berlin.
  
  Problem Conclusion:
  For the calculation of the new business date, we change timezone
  of the original date to the same as the workschedule.
  During the calculation we process day difference caused by
  timezone shifts.
  We return the calculated date in the timezone of the original
  date.
