Monkey Patching Time.strftime not being picked up by Time class

Question

I need to Monkey patch strftime in Ruby 1.8.7 with Rails 2.3 on Windows. In config\initializers I put this time_patch.rb file (code below) but it does not seem to be picking up:

if RUBY_PLATFORM =~ /mingw32|mingw64|mswin32|mswin64/

  class Time
    alias_method :original_strftime, :strftime
    def strftime(fmt)
      hour12 = "%2d" % ((hour + 11) % 12 + 1)
      original_strftime(fmt.gsub(/%l/, hour12))
    end
  end

end

I renamed the method to def blorping and did Time.methods from the Rails console but did not see the new method.

What do I need to do to get it to work?

It is showing there... what did I do wrong; i.e. how do I get it added to the Time class? — ScottJShea, Apr 04 '12 at 20:29

You're checking the class methods when using Time.methods, so what you want is something like Time.instance_methods to be sure it's patched correctly.

Thank you! This exposed other issues I had with the environment/tests – ScottJShea Apr 04 '12 at 21:16

You can also check `Time.instance_method(:strftime).source_location` in Ruby 1.9 to see where the method is defined. The internal one should return `nil`, a sign it's probably implemented in C in the Ruby VM, but yours would show the source location. – tadman Apr 04 '12 at 21:42
I do not think `source_location` is available to me in the Ruby 1.8.7 I am tied to. – ScottJShea Apr 04 '12 at 22:03
