RSpec time stubbing without Timecop

time_spec.rb

#Timecop is fun, but you don't need a whole gem for that. Just use
#Time.stub(:now), e.g.

describe "time" do
  before do
    @fake_time = Time.now
    Time.stub(:now) { @fake_time }
  end
  it "is equal" do
    Time.now.should == Time.now  # now it passes
  end
  it "is close" do
   Time.now.should be_within(0.1).of(Time.now)
  end
end

#It's easy to move @fake_time around in the middle of a spec, too, to
#simulate time passing or to zap over to e.g. the moment when daylight
#savings happens.
