Order of arguments for the == comparison matters for certain Date & TimeWithZone situations

[smtheard]

[13] pry(main)> Date.today - 1 == Date.today - 24.hours
=> false
[14] pry(main)> Date.today - 24.hours == Date.today - 1
=> true
[15] pry(main)> (Date.today - 1) == (Date.today - 24.hours)
=> false
[16] pry(main)> (Date.today - 24.hours) == (Date.today - 1)
=> true

Date#== vs ActiveSupport::TimeWithZone#==

[22] pry(main)> (Date.today - 1).class
=> Date
[23] pry(main)> (Date.today - 24.hours).class
=> ActiveSupport::TimeWithZone

should at the very least return the same result.. likely false.

I can't reproduce this. @smtheard which version of Rails are you using? Also which time zone you are using to configure your application? It would be great if you can share an example application which reproduces this behaviour.

Ah! this was on rails 3.2. I don't have a rails 4 environment at the moment, and didn't think to check it on there. I'll assume that since you can't repo, it is fixed in rails 4.
