Rails - Apr 2006 - Problem with RSS feed from Rails Recipes

I''m trying to add an RSS feed to my app, and am going through the
Rails Recipes chapter on doing so.  I get the following error when I
request the feed:

undefined method `gmtime'' for #<DateTime:
1963061961/800,0,2299161>
...
7:     xml.pubDate CGI.rfc1123_date(@posts.first.created_on)

Any idea what''s up?

Also, checking out the RSS feed in NetNewsWire, it just says "Untitled
Source" and has no items.  I validated the feed and it validates fine.
 The raw XML looks exactly like the example in Rails Recipes.  Not
sure what''s wrong with it.

hrm..I guess there''s a problem with how Rails handles
datetime''s in
PostgreSQL?  Not sure.  Anyway I did a search on how to convert a
DateTime to a Time (since DateTime doesn''t respond to #gmtime).  Put
this code in lib/date_time.rb

class DateTime
  def to_time
    Time.mktime(year, mon, day, hour, min, sec)
  end
end

required it in environment.rb, and changed the builder template code to
xml.pubDate CGI.rfc1123_date(@posts.first.created_on.to_time)

Works for me.  If I''m doing something wrong, I''d like to know
about
it, but I think it may just be a problem with Rails and postgres.
