[TYPO3-english] Header date in file link content: 1970…

[Gregory Loichot]

Hello,

I'm working on a TYPO3 4.5.8 and I'm trying to insert a file link 
content on a page. In this content, you can set an "header date": I 
choose 01-01-2012. In frontend, TYPO3 displays 01-01-1970.

I do not know how to solve this problem. An idea to help me ?

Thanks a lot,
Greg
