ActiveRecordを指定日時範囲内で取得する方法

from = Time.zone.parse("2009-10-06")
to = from + 1.day
Hoge.find(:all, :conditions => {:updated_at => from...to})

#出力されるSQL例: 
Hoge Load (0.0ms)   SELECT * FROM `hoges` WHERE (`hoges`.`updated_at` >= '2009-10-06 15:00:00' AND `hoges`.`updated_at` < '2009-10-07 15:00:00')
