I do that a lot Mirek

I am testing things out, I added a field TESTING to my products table. I added a Testing editdate to the layout for editing prodcuts.
When I save a testing date to my database, it's stored as yyyy-mm-dd, while my region is supposed to put year last. I'd like to use my region to manage the format, as that would make the code more generally usable (for later sharing).

When I reload the info into my editdate field, the field is colored light red... doesn't that indicate invalid value?
