----------------------------------------
I am facing this error only in Ruby 2.2.0 as I recently upgraded to latest Ruby 2.2.0

Here is the console log

~~~
2.2.0 :008 > Time.zone.parse("2014-12-29 20:16:32 -0400")
NoMethodError: undefined method `year' for nil:NilClass
	from /.rvm/gems/ruby-2.2.0/gems/activesupport-3.2.18/lib/active_support/values/time_zone.rb:275:in `parse'
	from (irb):8
	from /.rvm/gems/ruby-2.2.0/gems/railties-3.2.18/lib/rails/commands/console.rb:47:in `start'
	from /.rvm/gems/ruby-2.2.0/gems/railties-3.2.18/lib/rails/commands/console.rb:8:in `start'
	from /.rvm/gems/ruby-2.2.0/gems/railties-3.2.18/lib/rails/commands.rb:41:in `<top (required)>'
~~~

Whereas same works fine in Ruby 2.1.2

~~~
2.1.2 :001 > Time.zone.parse("2014-12-29 20:16:32 -0400")
 => Tue, 30 Dec 2014 00:16:32 UTC +00:00
~~~

Am I doing something wrong here? Do I need to use any other gem to make this work. Some 700 specs fail for my project after upgrading to Ruby 2.2.0 due to this undefined method 'year' errors.

Would highly appreciate your immediate help in this regard. Thanks in advance.
