How to change the default Date format For Webi Report

hi,

The default Date format of webi reports is mm/dd/yy

I wish to change the default date format to mm/dd/yyyy so that whenever

i drag a date from the universe it is automatically displayed in this format

and i dont have to manually format it everytime.

Is there anywhere where the default date format for all reports in webi can

be changed. and changes in xml files.

Thanks,
