BUG: org-time-stamp

Hello everybody,

when I'm on it, there seems to be a bug in org-time-stamp:

Today is <2007-04-03 Di>, when I'm in an org-file and i do `C-c .' and
just insert `4', i get a time-stamp for today (<2007-04-03 Di>). To
get the desired <2007-04-04 Mi>, i have to insert `4-4'.

I remember this worked in an older version of org.

I'm on 
"GNU Emacs 22.0.94.1 (i386-pc-linux-gnu, GTK+ Version 2.6.4)
 of 2007-02-23 on pacem, modified by Debian"
with "Org-mode version 4.69a",
but I could reproduce this behaviour on windows to.
