Sitecore webforms for marketers datetime issues

We are in the process of upgrading sitecore from 6.5 tot 7.2, and the webforms for marketers module from 2.3 to 2.4

If I submit a form, for example on 0900, log in to the sitecore admin, and open the Forms Report, everything is inserted correctly, except for the "Created" field, which shows the time plus 2 hours -> 1100

If I navigate the sqlite database using SQLite Manager (a firefox plugin) I see that the Timestamp column on the Form table shows the time minus 2 hours -> 0700

The code is in the sitecore.Forms.Core .dll, which I cant debug because I dont have a .pdb file. I`ve looked into the Sitecore.Forms.Config file if I should add some cultureinfo, but cant find anything

Datetime.Now gives the correct datetime if I render it on a page, and if I create items in the sitecore admin, the right dates are inserted.

Does anyone know how this can happen?
