+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.

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.
-=item *
-
-C<TIMESTAMP> values are written with precision of 4 numbers after the decimal
-point for seconds, but read with only second precision.
-
-If you know of a session variable we can set to control how timestamps look as
-strings, please let us know (via RT.)
-
-Otherwise we'll need to rewrite the produced SQL for timestamps, at some point.
