=head1 NAME
Rose::DB::Object::Metadata::Column::Time - Time column metadata.
=head1 SYNOPSIS
use Rose::DB::Object::Metadata::Column::Time;
$col = Rose::DB::Object::Metadata::Column::Time->new(...);
$col->make_methods(...);
...
=head1 DESCRIPTION
Objects of this class store and manipulate metadata for time 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>. Inherited methods that are not overridden will not be documented a second time here. See the L<Rose::DB::Object::Metadata::Column> documentation for more information.
=head1 METHOD MAP
=over 4
=item C<get_set>
L<Rose::DB::Object::MakeMethods::Generic>, L<date|Rose::DB::Object::MakeMethods::Time/time>, ...
=item C<get>
L<Rose::DB::Object::MakeMethods::Time>, L<date|Rose::DB::Object::MakeMethods::Time/time>, ...

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 L<Time::Clock> object. VALUE maybe returned unmodified if it is a valid time 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<precision [INT]>
Get or set the precision of the time value. The precision is the total count of digits in the whole time. For example, 12:34 has a precision of 4, and 12:34:56.12 has a precision of 8. The precision value must be 2, 4, or greater than or equal to 6. The default precision is 6. When the precision is set, the L<scale|/scale> is also set automatically.
=item B<scale [INT]>
Get or set the integer number of places past the decimal point preserved for fractional seconds. The default scale is 0. When the scale is set, the L<precision|/precision> is also set automatically.
Returns "time".
=item B<type>
Returns "time".
