 Recent changes to mysql2date seem to have introduced a timezone bug
 offset.

 I am seeing this in lastbuilddate in RSS feeds which uses
 get_feed_build_date(). get_feed_build_date() retrieves a set of modified
 times from the database in GMT format.

 Then it sends the latest one to mysql2date for formatting with 'r' as the
 chosen format. mysql2date is adding a timezone offset with the
 wp_timezone() function.

 The result in the RSS feed is a GMT time with an incorrect timezone offset
 (should be +0), based on the timezone set in WP admin.

 In our case, our WP timezone is -8. RSS validation fails because the
 lastbuildtime is up to 8 hours in the future.
