Setting system time in rspec tests without changing system clock

I'm working on getting a rails 3 application ready to use time zones. My development machine is in EDT and the servers I'm hosting on are in UTC. Is there a way in my rspec tests to change the system time zone ruby is using so that I'm running tests using the same system time zone without having to change the system clock on my computer? I've looked into Delorean and Timecop and they're not what I'm looking for. I'm looking for something like

Time.system_time_zone = "UTC"

...and then Time.now would return the UTC time instead of whatever my system time zone is set to.

before {Time.stub(:now) {Time.now.utc}}

With this, anywhere Time.now is called in your tests, it will return your system's time in UTC.

Example:

describe Time do
  before {Time.stub(:now) {Time.now.utc}}

  it "returns utc as my system's time" do
    Time.now.utc?.should be_true
  end
end

Rails gives you precisely what you are looking for:

Time.zone = "UTC"

Look at http://api.rubyonrails.org/classes/Time.html#method-c-zone-3D for more information.
