+=head1 NAME
+
+DBIx::Class::InflateColumn::DateTime - Auto-create DateTime objects from date and datetime columns.
+
+=head1 SYNOPSIS
+
+Load this component and then declare one or more
+columns to be of the datetime, timestamp or date datatype.
+
+ package Event;
+ __PACKAGE__->load_components(qw/InflateColumn::DateTime/);
+ __PACKAGE__->add_columns(
+ starts_when => { data_type => 'datetime' }
+ );
+
+Then you can treat the specified column as a L<DateTime> object.
+
+ print "This event starts the month of ".
+ $event->starts_when->month_name();
+
+=head1 DESCRIPTION
+
+This module figures out the type of DateTime::Format::* class to
+inflate/deflate with based on the type of DBIx::Class::Storage::DBI::*
+that you are using. If you switch from one database to a different
+one your code should continue to work without modification (though note
+that this feature is new as of 0.07, so it may not be perfect yet - bug
+reports to the list very much welcome).

+=head2 register_column
+
+Chains with the L<DBIx::Class::Row/register_column> method, and sets
+up datetime columns appropriately. This would not normally be
+directly called by end users.
