How can I duplicate the Ruby core class name and still use that main class in my class?

I am creating a very limited time class in which I want to use the time class parsing method. So I get something like this ...

class Time
    def parse(str)
         @time = # I want to use Time.parse here
    end
end

How can I break out of my newly defined time class and access the core of the Time Class without renaming my class?

require 'time'
class Time
#Opening the singleton class as Time.parse is a singleton method
  class << self
    alias_method :orig_parse, :parse
    def parse(str)
      @time = orig_parse str
    end
  end
end

You can now refer to the old parsing method using Time.orig_parse
