 Just tested it with a brand new WordPress local installation without any
 other plugins or themes to make sure that this problems is (so a presume)
 a core problem.

 When validating my RSS feed with https://validator.w3.org/feed/ it gives
 the following only error:


 {{{
 line 15, column 46: lastBuildDate must be an RFC-822 date-time: Mi, 16 Sep
 2015 16:31:18 +0000
 }}}

 this is the line mentioned:


 {{{
 <lastBuildDate>Mi, 16 Sep 2015 16:31:18 +0000</lastBuildDate>
 }}}

 Help says: ''Common errors include localizing the month name or the days
 of the week, not using the exact abbreviation provided by the
 specification, or attempting to use a time zone name that is not listed.''

 So I switched from a German to English settings which gives me the
 following RSS date:


 {{{
 <lastBuildDate>Wed, 16 Sep 2015 16:31:18 +0000</lastBuildDate>
 }}}

 This line now validates without any problems.

 I think this should be fixed as many people (so do I) rely on a valid RSS
 feed. Better save than sorry. It should not be a big issues as all other
 dates used inside RSS are valid – even in a German RSS feed.
