Date format in a Release plan

Hi
I have the constraint date attribute displayed in a release plan (Work Breakdown and schedule) . However, even though my local is set to English (Australia) it is displaying the date in mm/dd/yyyy format.  This can be dangerously confusing to people used to the correct date format of dd/mm/yyyy for the English (Australia) local.
Is there any way to change the date format in a release plan ?

Thanks in advance
