So I was getting this crazy value for the total time to run my Rspec tests. It was like a bizarre decimal. I never really cared until I started to try to speed up my tests.
It took me longer to find the solution than it took to fix it. If you are not getting a actual positive number in Rspec tests it might be Timecop. We are using Timecop and the time was frozen, hence the crazy total time. After running a test using Timecop, just add Timecop.return.
Piece of cake!!
