wine users - Jul 2005 - set date format

Hi list, 

I want to run a windows app which saves a date format in a text file.
When this application is run in windows, it uses the date format
dd-mm-yyyy hh:mm:ss (24 hour clock). 

However, when I run it under wine, it saves dates in the wrong date
format: mm/dd/yyyy h:mm:ss (so, 12 hour clock with am/pm). 

Is there a way to set wine up that it uses another date format? 

I'm using RedHat 9

thanks, Rinke
