NAME

Top

Form::Processor::Field::DateTimeManip - Free-form date/time input

SYNOPSIS

Top

See Form::Processor

DESCRIPTION

Top

This field uses the scary and bloated Date::Manip module to allow free-form date input (e.g. "Last Tuesday in December").

IIRC, timezone handling in Date::Manip is broken.

Widget

Fields can be given a widget type that is used as a hint for the code that renders the field.

This field's widget type is: "text".

Subclass

Fields may inherit from other fields. This field inherits from: "Field".

DEPENDENCIES

Top

DateTime, DateTime::Format::DateManip
