I am not the Ruby aficionado yet, if I have created_on …timestamp.
What is a ruby way of getting the hours/minutes/seconds ago. is there
some class that has this implemented.

For example:

I think the rails team extended the Time class for this reason

Module
ActiveSupport::CoreExtensions::Numeric::Time
In:
vendor/rails/activesupport/lib/active_support/core_ext/numeric/time.rb
http://api.rubyonrails.org/files/vendor/rails/activesupport/lib/active_support/core_ext/numeric/time_rb.html

Enables the use of time calculations and declarations, like 45.minutes +
2.hours + 4.years.

If you need precise date calculations that doesn?t just treat months as
30 days, then have a look at Time#advance.

Sorry, also look at the method (rails only) distance_of_time_in_words
(ActionView)

Look at distance_of_time_in_words_to_now
