// app/assets/env/test/time.js
window.__rails_test_time = Date();
// Or for you CS guys
@.__rails_test_time = Date()

In your JS that uses a cached Time.now-style date object, use this for assignment:
var now = window.__rails_test_time || Date();

Then conditionally include your test JS like so:
= javascript_include_tag "env/test/time" if Rails.env.test?
