Encarta RSS Feeds in Windows Vista Sidebar Gadget

I want to find a solution for this problem:

RSS feeds from MSN Encarta, when loaded in Vista's sidebar on a "Feed 
Headlines" gadget, display an incorrect date *Sat Dec 30* as the date for 
each of their entries. This way they are not shown at their correct position 
in the list, between other news entries, and new items never get on top, to 
be seen. You should correct the dates asap. Note that when loaded in Internet 
Explorer 7 newsreader, the dates are retreived correctly.

Here are the MSN Encarta feeds:

I tried to contact MSN Encarta support regarding this issue, but they 
answered that it's a Windows Vista issue and informed me that I should 
contact the Vista team instead. However, I don't feel this is right, because 
only the MSN Encarta feeds are showing the incorrect date in the Sidebar's 
Feed Gadget of Windows Vista -- no other feeds, including from Microsoft, 
suffer of this issue. Maybe some technical folks from MSN Encarta will see my 
question here in case that the support lady doesn't forward it to the right 
person.

Thanks in advance for letting me know if this issue is resolved or whatever 
resolution/workaround anyone finds.
