Automatic Re-recording

Over time, your cassettes may get out-of-date. APIs change and sites you
scrape get updated. VCR provides a facility to automatically re-record your
cassettes. Enable re-recording using the :re_record_interval option.

The value provided should be an interval (expressed in seconds) that
determines how often VCR will re-record the cassette. When a cassette
is used, VCR checks the earliest recorded_at timestamp in the cassette;
if more time than the interval has passed since that timestamp,
VCR will use the :all record mode to cause it be re-recorded.

Background
Given
a previously recorded cassette file "cassettes/example.yml" with:
--- 
http_interactions: 
- request: 
    method: get
    uri: http://localhost:7777/
    body: 
      encoding: UTF-8
      string: ""
    headers: {}
  response: 
    status: 
      code: 200
      message: OK
    headers: 
      Content-Length: 
      - "12"
    body: 
      encoding: UTF-8
      string: Old Response
    http_version: "1.1"
  recorded_at: Tue, 01 Nov 2011 04:58:44 GMT
recorded_with: VCR 2.0.0
And
a file named "re_record.rb" with:
start_sinatra_app(:port => 7777) do
  get('/') { 'New Response' }
end

require 'vcr'

VCR.configure do |c|
  c.hook_into :fakeweb
  c.cassette_library_dir = 'cassettes'
end

VCR.use_cassette('example', :re_record_interval => 7.days) do
  puts Net::HTTP.get_response('localhost', '/', 7777).body
end
Scenarios
Cassette is not re-recorded when not enough time has passed
Given
it is Tue, 07 Nov 2011
When
I run ruby re_record.rb
Then
the output should contain "Old Response"
But
the output should not contain "New Response"
And
the file "cassettes/example.yml" should contain "Old Response"
But
the file "cassettes/example.yml" should not contain "New Response"
