ActiveSupport::TimeWithZone in Range performance bug

Will have more than 5 seconds execution time with both Rails 2.3.11 and 3.0.7 on Ruby 1.8.7.
The problem don't appear on Ruby 1.9.2.

Also the following code doesn't have performance issue:

    I can confirm it happens on Ruby 1.8.7 and Rails 3.0.0, the example line takes 10+ seconds to run. The "doesn't have an issue" code works instantly as it did for you as well.

    I've found the bug and I'm creating patch.
