# RAILS_ROOT/config/initializers/datetime.rb
Time::DATE_FORMATS[:date] = "%a %b %d, %Y"
Time::DATE_FORMATS[:time] = "%I:%M%p"
# ...

Next I set up a helper function which will string together the :date and :time formats and remove the leading zero in the hour with the .gsub method on the string.

  # RAILS_ROOT/app/helpers/application_helper.rb
  def fulltime(created_at)
    created_at.to_s(:date)+" "+created_at.to_s(:time).gsub(/^0/,'').downcase
  end

In a view I’ll just pass the timestamp to the fulltime function

fulltime(@post.created_at)

The temporary solution is to not use attr_accessor and rather add the field to the database with the correct data type

 t.datetime :your_datetime_attribute_you_were_once_virtualizing

. Everything then works as normal. Oh well…
