How to get (print) the current time inside the watir gem file?

Question

I would like to print the current time the function is called inside the watir gem file.

Eg: inside /watir/element/select.rb

I need to print the current time, consider when the select_by is called. I tried by adding

require 'time'
..
..
def select_by
puts Time.now
..

But, it is showing error as

`NoMethodError in setup: undefined method `now' for Watir::Time:Class",
"C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/page-object-2.1.1/lib/page-object/platforms/watir/page_object.rb:1068:in `instance_eval'"
"(eval):1:in `process_watir_call'",`
