Sorry for spamming your issue list but think I found another problem. When I install the gem it installs the latest version of ActiveSupport as well as this is a dependency of the gem. No problem there if it wouldn't be for the new version of ActiveSupport. It installs 3.1.3 (at the time of writing) and that one doesn't seem to have the Time#advance method that is used in the gem. I downgraded ActiveSupport to 3.0.9 (as that's the stable version released before your last commit) and indeed, that one does not error out.
