DESCRIPTION

Rose::HTML::Form::Field::Time is a subclass of Rose::HTML::Form::Field::Text that only allows values that are valid times, which it coerces into the form HH:MM:SS AM/PM. It overrides the validate() and inflate_value() methods of its parent class.

This is a good example of a custom field class that constrains the kinds of inputs that it accepts and coerces all valid input and output to a particular format.
