DESCRIPTION

Rose::HTML::Form::Field::DateTime is a subclass of Rose::HTML::Form::Field::Text that allows only valid dates as input, which it then coerces to DateTime objects. It overrides the validate(), inflate_value(), and deflate_value() methods of its parent class.

Valid input is converted to the format "YYYY-MM-DD HH:MM:SS AM/PM" on output.

OBJECT METHODS

date_parser [PARSER]

Get or set the date parser object. This object must include a parse_datetime() method that takes a single string as an argument and returns a DateTime object, or undef if parsing fails.

If the parser object has an error() method, it will be called to set the error message after a failed parsing attempt.

The parser object defaults to Rose::DateTime::Parser->new().

output_format [FORMAT]

Get or set the format string passed to Rose::DateTime::Util's format_date function in order to generate the field's output value. Defaults to "%Y-%m-%d %I:%M:%S %p"

time_zone [TZ]

If the parser object has a time_zone() method, this method simply calls it, passing all arguments. Otherwise, undef is returned.
