First, You posted in the job board. Post in the right section next time ;-)
Onto your question...
You could use the date() function:
Code:
<?php
echo date('m-d-Y'); // outputs 09-19-2009
?>
so on your insert statement, it would look something like this:
Code:
$date = date('m-d-Y');
$this->db->insert('mytable', $date);
If you want more control, down to the second, you could use Epoch time. Look on the php.net manual for the time() function.
