CakePHP inserting timestamp, how to?

Question

I would like to save timestamp value into column.

If i trying to do by this way:

$SessionData['valid_till'] = time() + WEEK;

I get right number value. But into column is already saved value like this:

0000-00-00 00:00:00

How can i do it right way in CakePHP?

Thanks for any advice.
