[opencms-dev] Cannot save dates earlier than 1970

[Marc Schlegel]

Hello

I need to store birthday information and the Editor gives me an error ( 
DoB[1]: ??? GUI_EDITOR_XMLCONTENT_VALIDATION_ERROR_2 ??? ) when I type a 
date earlier than 1970.

Example
10.1.1970 14:27 works
10.1.1969 14:27 doesnt work

Its quite urgent, cause I want to publish the site in the next days.

Thanks
