=head1 NAME
Rose::DB::Object::Metadata::Column::Timestamp - Timestamp column metadata.
=head1 SYNOPSIS
use Rose::DB::Object::Metadata::Column::Timestamp;
$col = Rose::DB::Object::Metadata::Column::Timestamp->new(...);
$col->make_methods(...);
...
=head1 DESCRIPTION
Objects of this class store and manipulate metadata for timestamp columns in a database. Column metadata objects store information about columns (data type, size, etc.) and are responsible for creating object methods that manipulate column values.
This class inherits from L<Rose::DB::Object::Metadata::Column::Date>. Inherited methods that are not overridden will not be documented a second time here. See the L<Rose::DB::Object::Metadata::Column::Date> documentation for more information.
=head1 METHOD MAP
=over 4
=item C<get_set>
L<Rose::DB::Object::MakeMethods::Date>, L<timestamp|Rose::DB::Object::MakeMethods::Date/timestamp>, C<interface =E<gt> 'get_set', ...>
=item C<get>
L<Rose::DB::Object::MakeMethods::Date>, L<timestamp|Rose::DB::Object::MakeMethods::Date/timestamp>, C<interface =E<gt> 'get', ...>
=item C<set>

See the L<Rose::DB::Object::Metadata::Column|Rose::DB::Object::Metadata::Column/"MAKING METHODS"> documentation for an explanation of this method map.
=head1 OBJECT METHODS
=over 4
=item B<parse_value DB, VALUE>
Convert VALUE to the equivalent C<DateTime> object. VALUE maybe returned unmodified if it is a valid timestamp keyword or otherwise has special meaning to the underlying database. DB is a L<Rose::DB> object that is used as part of the parsing process. Both arguments are required.
=item B<type>
Returns "timestamp".
