strftime works like this:

sqlite> select strftime('%d-%m-%Y %H:%M:%S', datetime('now'));
2012-09-13 12:42:56

If you want to use it in a WHERE clause, replace datetime('now') with the datetime you want to match in the YYYY-mm-dd HH:MM:SS format.

Example:

SELECT *
  FROM t
 WHERE c = strftime('%d-%m-%Y %H:%M:%S', '2012-09-13 12:44:22');
--                   dd-mm-YYYY HH:MM:SS  YYYY-mm-dd HH:MM:SS
