undefined method `to_r' for 61200.0:Float - in Ruby 1.8.7

[swalberg]

I get the following error in ree 1.8.7 using Timecop 0.4.4 (or 0.4.1) and Rails 3.0. If I go back to Timecop 0.3.5 it works. It also works if I update to Ruby 1.9.3 (which unfortunately isn't an option for me at the moment). Have also tested this in a different Rails 3.2 project with the same results.

>> Timecop.freeze(Time.parse("2011-12-10 13:00-0400")) { puts DateTime.now }

This is a bug in REE that was patched even in MRI, http://bugs.ruby-lang.org/issues/4644.

Unless many others have this problem, my advice is to stick with 0.3.5 until you're off REE, or bug them to make a similar patch.
