Hi,
I'm trying to create issues by importing a csv file. It works, i can create project and issues, fields are correctly filled in.
But i have a problem with the creation date.
In the Look and Field page, i set the day/month/year like this

In my excel file, i set the Creation date: 31/12/2011
I also set "this file = creation date" during importation
But i have a error message:
What did i do wrong? 
thanks
Vincent
