# == Adding your own time formats in to_formatted_s
# You can add your own time formats by merging them into the DATE_FORMATS constant. Use a string with
# Ruby's strftime formatting (http://ruby-doc.org/core/classes/Time.html#M000297), or
# pass a lambda. The lambda yields the instance to_formatted_s is called on, so that calculations
# can be performed on that instance. This is handy when Ruby's strftime formatting is insufficient. See
# the +short_ordinal+ example below.
#
# See DATE_FORMATS for the list of built-in formats, and to_formatted_s for implementation details.
#
# === Examples:
# # config/initializers/time_formats.rb
# ActiveSupport::CoreExtensions::Date::Conversions::DATE_FORMATS.merge!(
# :month_and_year => "%B %Y",
# :short_ordinal => lambda { |time| time.strftime("%B #{time.day.ordinalize}") }
# )
#
# Calling it on a Time instance:
#
# Time.now.to_s(:short_ordinal)
# Converting dates to formatted strings, times, and datetimes.
