Rails: display last deployment date in web application

Question

I would like to show in our application when the last production rollout was made, as a means to demonstrate the constant desire for improvement, etc. etc.

From head to toe I am thinking of getting last_updated_at from one of the files, but I would like to hear other thoughts.

What is the best way to dynamically set the last release date?

Thank,

Josh

Thanks mpd, which pointed me in the right direction.

For those interested in doing something like this, this is a quick and dirty method that can probably be refined and reorganized.

app/controllers/application_controller.rb :

private 

def app_last_updated_at
  if File.exist?(RAILS_ROOT + "/REVISION")
    timezone = "Mountain Time (US & Canada)"
    @app_last_updated_at = File.atime(RAILS_ROOT + "/REVISION").in_time_zone( timezone )
  else 
    @app_last_updated_at = "Not Long Ago."
  end
end

, ( - ).

, :before_filter application_controller.rb.

before_filter :app_last_updated_at

, , - :

<%= 
unless @app_last_updated_at.nil? 
  if @app_last_updated_at.is_a? Time 
@app_last_updated_at.to_s(:long)
  else
@app_last_updated_at 
  end
end
%>
