[dataobject] insert date

[steeldevil]

Hii,

I use the http://pear.php.net/manual/en/package.database.db-dataobject.php to interact with my database.

Now i have a timestamp field in a database table so, i tried many things but nothing seems to work the value is still the default (0000-00-00 00:00:00).

I tried many things from this page:
http://pear.php.net/manual/en/package.database.db-dataobject.intro-casting.php

but nothing seems to work

for example:
$this->startDate = DB_DataObject_Cast::dateTime();
$this->startDate = DB_DataObject_Cast::sql('NOW()');
....


the value is still 0000-00-00 00:00:00.

When i turn the debug level to 5 and read the query, the date field was not added to the query....

At the top of the page i see this message:
"This is experimental!, although it is documented, it currently only supports a limited amount of databases (send me fixes if you want it to support your favorite database), and the internal operations/API may change in the future.. "


I use Mysql... is there an other method i just want to insert a date.
I dont want to do it with a raw query because there are many date fields in the database.
