[TYPO3-project-formidable] rdt_date: different behaviour when submitted

[Pablo Santamaria Lois]

Hi to all!

I would like to share with you a problem which arose to me while working with renderlet:DATE.

Using a formidable template in edition mode, I've seen the following behaviour:
A) if I change renderlet's value using the widget, and then submit the form, value stored in DB seems to be the chosen one. (OK)
B) however, if I submit the form without change renderlet's value, date in DB WILL be changed, to a different timestamp. (current value - 7200)

Let's see an example:
A) I've selected 14/10/2009 in renderlet's widget, so in DB will be stored:
1255478400. This timestamp means [1]:
- GMT: Wed, 14 Oct 2009 00:00:00 GMT
- My timezone: Wed 14 Oct 2009 02:00:00 AM CEST

B) With previous timestamp in DB, I didn't change renderlet's value, but submitted the form. In DB will be stored the following: 1255471200, which means:
- GMT: Tue, 13 Oct 2009 22:00:00 GMT
- My timezone: Wed 14 Oct 2009 12:00:00 AM CEST

As far as I know, TYPO3 stores timestamps in BD in GMT format, so in case B), is renderlet:DATE managing correctly timezones?

In case B), Why date in BD is modified although it wasn't changed using the renderlet?

Any help from you will he highly appreciated.
Thanks in advance, Pablo.
