Dateformat convert

[eluser]33cent[/eluser]
Hi,

i'm using jQuery datepicker in my new project, to select date for my entry, and format of the date is dd.mm.yyyy. But, in the database, i want to use format yyyy-mm-dd

Have no idea, how to convert date format "on-the-fly" during insert.
I tried something like: "date" = $this->datemodel->convertdate($_POST['date']); but without success.
