+=head1 NAME
+
+DBIx::Class::Storage::DBI::InterBase - Driver for the Firebird RDBMS
+
+=head1 DESCRIPTION
+
+This class implements autoincrements for Firebird using C<RETURNING>, sets the
+limit dialect to C<FIRST X SKIP X> and provides preliminary
+L<DBIx::Class::InflateColumn::DateTime> support.
+
+For ODBC support, see L<DBIx::Class::Storage::DBI::ODBC::Firebird>.
+
+To turn on L<DBIx::Class::InflateColumn::DateTime> support, see
+L</connect_call_datetime_setup>.

+=head2 connect_call_datetime_setup
+
+Used as:
+
+ on_connect_call => 'datetime_setup'
+
+In L<connect_info|DBIx::Class::Storage::DBI/connect_info> to set the date and
+timestamp formats using:
+
+ $dbh->{ib_time_all} = 'ISO';
+
+See L<DBD::InterBase> for more details.
+
+The C<TIMESTAMP> data type supports up to 4 digits after the decimal point for
+second precision. The full precision is used.
+
+The C<DATE> data type stores the date portion only, and it B<MUST> be declared
+with:
+
+ data_type => 'date'
+
+in your Result class.
+
+Timestamp columns can be declared with either C<datetime> or C<timestamp>.
+
+You will need the L<DateTime::Format::Strptime> module for inflation to work.
+
+For L<DBIx::Class::Storage::DBI::ODBC::Firebird>, this is a noop and sub-second
+precision is not currently available.

+C<last_insert_id> support only works for Firebird versions 2 or greater. To
+work with earlier versions, we'll need to figure out how to retrieve the bodies
+of C<BEFORE INSERT> triggers and parse them for the C<GENERATOR> name.
