[Typo3] getting crdate within FCE via typoscript

[Nikolas Hagelstein]

hi,

i need to fetch the crdate of the current
tt_content element (FCE instance)
Via typoscript. 

10=TEXT
10.field=crdate
or
10.field=field:crdate

does not work 
debug:data  only returns  all FCE datastructur fields.
Any ideas?

cheers,
             Nikolas
