[Typo3-dev] default date

[Ursula Klinger]

Hi,

who can help me. For the moment I make an extension to extend the page
header by revision date. I use the kickstarter for this extension and
as field type I use the date field. In the TCA array it looks like this.

"tx_ptpageext_reviewdate" => Array (
 	"exclude" => 1,
 	"label" => "LLL:EXT:pt_pageext/locallang_db.php:pages.tx_ptpageext_reviewdate",
 	"config" => Array (
 		"type" => "input",
 		"size" => "8",
 		"max" => "20",
 		"eval" => "date",
 		"checkbox" => "0",
 		"default" => "0"
 	)
),

If the checkbox is checked in the BE as default date the current date is set. 
I want that the current date + 1 year is set. Is there any possibily to
manipulate the dafault date?

Thanks

Ursula
