[KDE4] Desktop plasmoid - sort by date

[XMath]

Hello,
just switched from KDE 3.5.10 to 4.2.4, and playing around a little bit.

One thing that takes me wonder:
Having a folder view on my desktop and select to sort this view by date gives "weird" result. To be specific the result is different to the sorting order in dolphin or konqueror.

Anyone else facing this?
Did not find a bug on bugs.kde.org for it.
