created and modified in CakePHP 1.1

A simple question: in both CakePHP 1.2 and 1.3, created and modified fields will be automatically populated:

By defining a created or modified field in your database table as datetime fields, CakePHP will recognize those fields and populate them automatically whenever a record is created or saved to the database (unless the data being saved already contains a value for these fields).

A preliminary search of the Cookbook finds no such section for CakePHP 1.1开发者_如何学JAVA. Is this functionality in 1.1 at all, or was it introduced with 1.2? If the former, bonus points given for ideas on how to replicate it in 1.1...
