Custom Property Date Format

Hi all

I have added custom property of type date.

In KM Navigation iView, I am displaying that property. But it is showing in

MM-DD-YYYY Format.

I want to show it in DD/MM/YYYY (or DD-MM-YYYY)

I have changed the

Additional Metadata : alignRight,customFormat=dd/MM/yyyy HH:MM

But still its not working. Same change I did for <b>cm_modfied</b> property and it worked.

Pls suggest the solution.
