[opencms-dev] Cannot save dates earlier than 1970

[Marc Schlegel]

I was about to open a bug, but in case there is something I searched before.

And as it looks, it has already been assigned  ( see 
http://bugzilla.opencms.org/show_bug.cgi?id=1481 )

@Devs: Can we expect a fix for this in the next release? Would be great.
