Title: Specify rspec dependendy ~> 2.9.0

I tried with rspec 2.8.0 and got this error
``` shell

```
indeed format_duration was added in version 2.9.0 by [this](https://github.com/rspec/rspec-core/commit/76be2a821876db5b766fd276d2cb9f92174903a1) commit.

Thus my pull request to be more specific about the gem requirements.
