Store original dates in the model

I found useful to have the original DB dates available in the model, to perform comparisons.
By defining a public property $_original_dates in your model you will have it populated as an array with original DB values.

Example:
class MyModel extends CActiveRecord
{
    [...]

    public $_original_dates = array ();

    [...]

Then you can access Model->_original_dates ['date_field']
