>> Vip.first.created_at.class
=> ActiveSupport::TimeWithZone

>> Vip.first.expired_at.class
=> ActiveSupport::TimeWithZone

一樣的 class 喔，但是實際上不同：

>> Vip.first.created_at.to_i
=> 1252402216

>> Vip.first.expired_at.to_i
NoMethodError: undefined method `to_i' for DateTime

* * *

>> Vip.first.expired_at.to_i
NoMethodError: undefined method `to_i' for DateTime

>> Vip.first.expired_at.to_time.to_i
NoMethodError: undefined method `to_i' for DateTime

rails 都亂改 core method... to_time 騙人！
