If your code uses Date#now, always make sure you stub it in your

Yes, but the OP's question was why do two "same" date objects compare
as different. This is a typical problem with floating-point and
anything that counts time. I used DateTime.now in my sample code
below, but certainly I agree that specifying an exact object either by
stubbing or explicit constant specification is a better idea. There
will be cases, however, where a strict equality test can't be trusted
and one must compare something as being within some "close" tolerance.

I monkeypatched DateTime (aieeeeee!) to get this effect. A custom
matcher is probably a better solution. Here's the monkeypatch:
require File.dirname(__FILE__) + '/../spec_helper'
class DateTime
def close?(other_date, difference)
(other_date.to_time.to_i - DateTime.now.to_time.to_i).abs <
difference
end
end
#Delete this context and add some real ones
context "should be able to create a project viewer" do
fixtures :project_viewers
specify "fixtures should load two ProjectViewers" do
pb = ProjectViewer.create(:comments => 'a
comment', :last_viewed_at => DateTime.now)
pb.last_viewed_at.should_be_close(DateTime.now, 100)
end
end
