Dlaczego mój Model.where() zwraca pustą tablicę (gdy jestem pewien, że są dopasowania)?

Question

Co robię nieprawidłowo, to daje mi pustą tablicę z tego polecenia?

Item.where(:load_date => Date.today + 2) 

Oto moja Szyny konsoli:

.9.3-p194 :024 > Item.first.load_date 
Item Load (0.3ms) SELECT "items".* FROM "items" LIMIT 1 
=> Fri, 24 May 2013 
1.9.3-p194 :025 > Item.where(:load_date => Date.today + 2) 
Item Load (0.5ms) SELECT "items".* FROM "items" WHERE "items"."load_date" = '2013-05-24' 
=> [] 
1.9.3-p194 :026 > Item.first.load_date == Date.today + 2 
Item Load (0.3ms) SELECT "items".* FROM "items" LIMIT 1 
=> true 

Element Model:

... 
# load_date  :date 
... 

class Item < ActiveRecord::Base 
attr_accessible :bt_num, :dept, :formula, :item_code, :load_date, :prod_comments, :qc_comments, :qc_tech, :qty_in_kg, :qty_in_liters, :rm_ok_by, :series, :status, :time_to_produce, :vat 
...
