=head1 NAME

Rose::DB::Object::Metadata::Column::Epoch - Seconds since the epoch column metadata.

=head1 SYNOPSIS

  use Rose::DB::Object::Metadata::Column::Epoch;

  $col = Rose::DB::Object::Metadata::Column::Epoch->new(...);
  $col->make_methods(...);
  ...

=head1 DESCRIPTION

Objects of this class store and manipulate metadata for columns in a database that store an integer number of seconds since the Unix epoch.  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 OBJECT METHODS

=over 4

=item B<parse_value DB, VALUE>

Convert VALUE to the equivalent L<DateTime> object.  VALUE maybe returned unmodified if it 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 "epoch".
