Yes, currently, because og_read calls new.  But using allocate in place 
of new will bypass the initialization of @tstamp

Example:

class Foo
   attr_accessor  :x, :y
   def initialize( x=nil, y=nil )
      @x = x
      @y = y
      @tstamp = Time.new
   end

   def create_date
      @tstamp
   end

end

f = Foo.allocate
p f.create_date # nil
