 When setting my site in English, the RSS feed says:
 '''<lastBuildDate>Wed, 30 Nov 2016 15:47:34 +0000</lastBuildDate>'''

 But when I set it up in Dutch, it says:
 '''<lastBuildDate>wo, 30 nov 2016 15:47:34 +0000</lastBuildDate>'''

 This date should be a valid RFC date. Otherwise feed validators won't
 validate the feed.

 '''Possible fix:'''
 {{{#!php
 <lastBuildDate><?php
 date = get_lastpostmodified( 'GMT' );
 echo $date ? mysql2date( 'D, d M Y H:i:s +0000', $date, false ) : date(
 'D, d M Y H:i:s +0000'
 }}}</lastBuildDate>
