The date field for each RSS feed varies for many providers, somtimes
depending on timezone
The different formats will have to be interpreted differently, perhaps the
providers have different ways of interpreting the standard.
Examples are:

Jyllandsposten (Denmark)
Thu, 20 Apr 06 11:37:00 +0200

CNN
Thu, 20 Apr 2006 05:58:42 EDT

MSDN
Wed, 11 May 2005 07:00:00 GMT

The last one is the only format directly supported by the .NET date
conversion by using the code "r"
For conversion of other strings you must make a custom format conversion (I
think!)
Am i right?
I have had a lot of trouble with this, for instance when trying to convert
the date to another format like yyyy-mm-dd
