how to set a DEFAULT value !!

for example, a table, 2 column
Table
------------------------------------------------------------
| lang_code | CHAR(2) | default: 'en' |
------------------------------------------------------------
| time | DATETIME | |
------------------------------------------------------------

I would like to do in SQL
" INSERT table VALUES (DEFAULT, NOW()); "

I use DBIx::Class and it seems not so easy....
When I do pupulate, I write like this..
$schema->populate(
'Table',
[ [ qw/lang_code
time/
],
(
[ $schema->source('Table')->column_info('lang_code')->{default_value},
'2006-04-24 12:13:23',
],
)
],
)

Question!
is there any simple way I can write like this?
$schema->populate(
'Table',
................
[ DEFAUT,
NOW(),
]
.......
)

thanks a lot!
