Rails - Apr 2006 - Strange errors in generated html

Hi!

This:
<%= javascript_include_tag :defaults %>
<%= stylesheet_link_tag ''doitwithstyle'' %>

generates this:
<script src="/javascripts/prototype.js?1144418901" 
type="text/javascript"></script>
<script src="/javascripts/effects.js?1144418901" 
type="text/javascript"></script>
<script src="/javascripts/dragdrop.js?1144418901" 
type="text/javascript"></script>
<script src="/javascripts/controls.js?1144418901" 
type="text/javascript"></script>
<script src="/javascripts/application.js?1144418901" 
type="text/javascript"></script>
<link href="/stylesheets/doitwithstyle.css?1144421253"
media="screen"
rel="Stylesheet" type="text/css" />

What are these numbers? I installed rails 1.1.1 (linux) today and i''ve 
got it on every rails page. I''m not sure if it was before. Everything 
works ok, just the generated code looks weird.

BTW. I''ve got warnings about RAILS_GEM_VERSION already defined
somewhere
else (one definition is in environment.rb). Should i do something about 
it or just leave it?

the numbers are random strings (current time??) added in development to  
force a reload of js and css files...

otherwise some browsers will cache the files...
its my undestanding that this is only in effect in development

These are not random, but simple file modification time: File.mtime().to_i.to_s
AFAIK their generation does not depend on environment, be it
development or production.
Whenever you modify your .js or .css string changes and browser will fetch new
version instead of using the cached one.
