[Typo3] TSConfig to set the date field on the tt_content object

[Courcy Michael]

Hi list

I want to have the date field automaticly set on the tt_content when a 
beuser create one

TCAdefaults.tt_content.date = 1   
generate 1-1-1970

TCAdefaults.tt_content.date.data = date:U   
doesn't work

TCAdefaults.tt_content.date.field = tstamp   
doesn't work either

documentation didn't bring the answer

Any help would be appreciated.
